Answer:
x = 65°
Step-by-step explanation:
The interior angle of the triangle and 140° are adjacent and supplementary, thus
interior angle = 180° - 140° = 40°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
105° is an exterior angle of the triangle, thus
x + 40° = 105° ( subtract 40° from both sides )
x = 65°
Answer:
.7,.38, .09,-.41, -.6
Step-by-step explanation:
25% for 90deg
15% for 54deg
10% for 36deg
All I did was put the degree number over 360 and moved the decimal place to the right twice :)
