Answer:
$50
Step-by-step explanation:
you multiply 1/4 with 200
this results in 50
1/4= .25
.25 x 200 = 50 !!!
Answer:
x=26 degrees (D)
Step-by-step explanation:
Let's say x is the angle.
90-x would be the complement of the angle
180-x is the supplement
We can make the equation
supplement-26=2complement as the question states that twice the complement is 26 less than the supplement.
We can now substitute the 90-x and 180-x in their respective positions to get (180-x)-26=2(90-x) if we simplify this we get 180-x-26=180-2x which if we take away 180-x from both sides we get that -26=-x or 26=x
