5. 6√3
6. x = 10√3 y = 30
7. x = 34 y = 17√3
8. 30
9. SinA = 3/5 CosA = 4/5
10. Tan20 = 9/x
Multiply both sides by x to get it on the other side
x(tan20) = 9
Divide 9 by tan20 to get x.
x = 9/tan20
x = 24.7
Answer:
10
Step-by-step explanation:
By the geometric mean theorem,
- 4/a = a/25
- 100=a² (cross multiply)
- a=10 (square root both sides and take the positive solution)
Answer:
the answer is 2.1
Step-by-step explanation:
using a calculator:
1. type in 4.2
2. multiply 4.2 by 1/2
3. the answer will then be shown as 2.1

Answer:
∠a = 50°
∠b = 130°
∠c = 130°
Explanation:
Following Vertical Angles Theorem:
A straight line has 180° angle measure, ∠c and ∠a lies on a straight line
Also, following vertical angle theorem:
