The sum of interior angles in a triangle is 180°
42° + 67° + other angle = 180°
109° + other angle = 180°
other angle = 180° - 109°
other angle = 71°
The measure of the other angle is 71 degrees
2/5 in decimal form would be 0.4
Answer:
68 degrees
Step-by-step explanation:
The straight horizontal line is a straight angle with 180 degrees it is split in a way that you know under the right angle, is another right ange making up part of the 180° line, add 22 and then subtract what you get from 180 to get 68.
A simpler way, add the angles in the X and 22 degree things and there is a right angle, 90 degrees, subtract 22 from 90 and get 68
Two different ways, either will work
Hope this helps!
