I’m pretty sure the answer is Meal A
Answer:
The angle measurement of a is 21.78°.
Step-by-step explanation:
Given : The triangle abc has a side lengths ac=13 and the hypotenuse ab=14.
To find : Whats the angle measurement of a ?
Solution :
In triangle abc,
The side length is the adjacent side of the angles a i.e. base = ac=13
The hypotenuse is ab=14.
Apply trigonometry in triangle abc,
Therefore, the angle measurement of a is 21.78°.
Answer:
m<1 = 90°
m<2 = 36°
Step-by-step explanation:
✔️m<2 + 54° = 90° (complementary angles)
m<2 = 90° - 54° (subtraction property of equality)
m<2 = 36°
✔️m<1 = m<2 + 54° (supplementary angles)
m<1 = 36° + 54°
m<1 = 90°
