Answer:
56 total
Step-by-step explanation:
Let the number of girls = x
Let the number of boys = 3x
x 1
=== = ==========
x + 28 3
Cross multiply
3x = x + 28 Subtract x from both sides
3x - x = 28 Combine
2x = 28 Divide by 2
x = 28/2
x = 14
Girls = 14
Boys = 14 + 28 = 42
Is the ratio 3 to 1?
42/14 = 3/1 Yes it does
Total number
14 + 42 = 56
The two angles, when added, should form a straight line.
A. ∠RST and ∠RSV form the line VT
B. ∠RST and ∠TSU form the line RU
C. ∠RST and ∠VSU form opposite angles with each other
D. ∠TSU and ∠USV form the line VT
E. ∠TSU and ∠RSV form opposite angles with each other
So, the answers are A, B and D.
Use the inverse of sin
Sin -1 ( 7/13)
= 32.6
