Step-by-step explanation:
4x + 12° = 64° ( vertically opposite angle )
4x = 64° - 12°
4x = 52°
x = 52° / 4
x = 13°
hence the value of x is 13°
1. No idea
2. Angle A
3. Line RT
4. NO, 4/2 = 2, 5/3 = Not 2
5.Asking someone else?
6. 6 ft.
7. 10.56, precisely
8. 90 degrees
9. 51 degrees
10. 24 ft.
we know that the multiplication comes first in the family then we start from left to right
4 x 5= 20
9-20 = -11
-11 + 6 = -5
there you go!
Sinx = cosb => x + b = 90 <=> b = 90 - 47 = 43o
Answer:
B. 30
Step-by-step explanation:
Boys to girls
2 : 3
Units of girls = 3
3 units = 18
1 unit = 18 ÷ 3 = 6
Total number of units = 2 + 3 = 5
5 units = 6 x 5 = 30
