Answer:
m<C = 36.87degrees
Step-by-step explanation:
Solve for the approximate measure of angle C.
From the given diagram;
AC is the hypotenuse
BC is adjacent to <C
Cos m<C = adj/hyp
Cos m<C = BC/AC
Cos m<C = 20/25
Cos m<C = 0.8
m<C = arccos (0.8)
m<C = 36.87degrees
Answer:
140°
Step-by-step explanation:
<u>Given:</u>
Dana draws a triangle with one angle that has a measure of 40∘.
<u>Question asked:</u>
What is the measure of the angle’s adjacent exterior angle?
Solution:
<u>As we know:</u>
<u><em>Sum of the adjacent interior and exterior angles is 180°.</em></u>
Interior angle = 40°
Adjacent exterior angle = ?
Interior angle + Adjacent exterior angle = 180°
40° + Adjacent exterior angle = 180°
<u>By subtracting both sides by 40°</u>
40° - 40° + Adjacent exterior angle = 180° - 40°
Adjacent exterior angle = 140°
Therefore, the measure of the angle’s adjacent exterior angle will be 140°.
