-1.9 = x/.5 given equation
multiply both sides by .5
.5(-1.9) = x/(.5) *(.5)
-.95 = x
check: -1.9 = -.95/ .5
Answer:
true
Step-by-step explanation:
Answer:
Value of x is 90°
Step-by-step explanation:
Why?Imagine it as a shape of circle.
Circle has a measurement total of 360°
Semi cirlcle(half of the circle) is equivalent to 180
Now,
The bottom semi circle has a 146°
The top has a 56°
You can simply compute it by subtracting them.

24 because the ratio is 5:8 and you have to multiply 5 by 3 to get 15
so you have to do the same thing to 8 and multiply it by 3 to get 24
