Answer:
60
Step-by-step explanation:
What we know:
- ABD is a straight angle, it measures 180 degrees
- Angle CBA + CBD = 180 degrees
- Angle GFH = CBA (they are alternate exterior angles)
Equation:
GFH + CBD = 180
Substitute:
3x + 6x = 180
Add:
3x + 6x = 180
9x = 180
Divide:
9x = 180
/9 /9
x = 20
Substitute:
GFH = 3x
GFH = 3(20)
GFH = 60
m<GFH is 60°
Answer C. base side length = 30.6 cm, height = 27.3 cm
Pentagon since it has 5 sides
Answer:
Jonny has 3 and a half apples left
Step-by-step explanation:
7/2=3.5
sin P = 24/26
cos P = 10/26
tan P = 24/10
sin Q = 10/26
cos Q = 24/26
tan Q = 10/24
you have the first part right. using Soh Cah Toa is the best way to find the trig function when given a labeled triangle.
remember the hypotenuse is the longest side and always across from the 90 degree angle.
