Answer:
Step-by-step explanation:
Since this is a right angled triangle:
tan(∅) = opposite side/adjacent side
In this triangle:
tan(25°) = x/19
x = 8. 86 ≅ 8.9
Answer:
1 224
Step-by-step explanation:
A^2 + b^2=c^2
So do 30 ^2 and 18^2
And add both
First one:
Supplementary = 180
Add the angles together to get 180
10x + 36 + 6x = 180
16x = 144, x = 9
Plug 9 into equation of angle RAS
10(9) + 36 = 126
Angle RAS = 126 degrees
Second question:
Exterior angle = sun of two opposite interior angles
54 degrees + 90 degrees = 144
Solution: the exterior angle is 144 degrees
