The angles in a triangle must add up to 180º.
If a triangle has a 32º angle and a 67º angle, what is the measurement of the third angle?
__º
__º
To find the measurement of the third angle, we subtract the sum of the given angles from 180º.
180º - (32º + 67º) = 81º
Therefore, the measurement of the third angle is 81º.
180º - (32º + 67º) = 81º
Therefore, the measurement of the third angle is 81º.
If two angles of a triangle add up to 110º, what is the measure of the third angle?
__º
__º
To find the measure of the third angle, we subtract the sum of the two given angles from 180º.
180º - 110º = 70º
Therefore, the measure of the third angle is 70º.
180º - 110º = 70º
Therefore, the measure of the third angle is 70º.
Find x in the figure.
one angle: 35º
second angle: 40º
third angle: x
one angle: 35º
second angle: 40º
third angle: x
To find x, we need to sum up all three angles of the triangle and subtract the given angles from 180º.
35º + 40º + x = 180º
Combining like terms, we have:
75º + x = 180º
To isolate x, we subtract 75º from both sides:
x = 180º - 75º
x = 105º
Therefore, the measure of the third angle, x, is 105º.
35º + 40º + x = 180º
Combining like terms, we have:
75º + x = 180º
To isolate x, we subtract 75º from both sides:
x = 180º - 75º
x = 105º
Therefore, the measure of the third angle, x, is 105º.
incorrect
Apologies for the mistake. Let's correct the solution:
Given information:
Angle 1: 35º
Angle 2: 40º
To find x, we can subtract the sum of the given angles from 180º:
x = 180º - (35º + 40º)
x = 180º - 75º
x = 105º
Therefore, the measure of the third angle, x, is 105º.
Given information:
Angle 1: 35º
Angle 2: 40º
To find x, we can subtract the sum of the given angles from 180º:
x = 180º - (35º + 40º)
x = 180º - 75º
x = 105º
Therefore, the measure of the third angle, x, is 105º.
Find d in the figure.
one angle: 50º
second angle: 70º
third angle: d
one angle: 50º
second angle: 70º
third angle: d
To find d, we need to sum up all three angles of the triangle and subtract the given angles from 180º.
Given information:
Angle 1: 50º
Angle 2: 70º
To find d, we can subtract the sum of the given angles from 180º:
d = 180º - (50º + 70º)
d = 180º - 120º
d = 60º
Therefore, the measure of the third angle, d, is 60º.
Given information:
Angle 1: 50º
Angle 2: 70º
To find d, we can subtract the sum of the given angles from 180º:
d = 180º - (50º + 70º)
d = 180º - 120º
d = 60º
Therefore, the measure of the third angle, d, is 60º.
Correct answers are:
180º
81º
70º
75º
120º
180º
81º
70º
75º
120º
Apologies for the confusion earlier. Let's solve the problem correctly this time.
Given:
One angle: 50º
Second angle: 70º
Third angle: d
To find the measure of the third angle, we can subtract the sum of the given angles from 180º:
d = 180º - (50º + 70º)
d = 180º - 120º
d = 60º
Therefore, the measure of the third angle, d, is 60º.
Given:
One angle: 50º
Second angle: 70º
Third angle: d
To find the measure of the third angle, we can subtract the sum of the given angles from 180º:
d = 180º - (50º + 70º)
d = 180º - 120º
d = 60º
Therefore, the measure of the third angle, d, is 60º.
