Answer: 26
Step-by-step explanation: Complementary angles are angles that add up to 90 degrees. So we use m<a+m<b=90 so let plug in
(4x+24)+ (3x-4)=90, then combine like with like.
7x+20=90
7x=70
x=10
Then let plug it in for angle B
(3(10)-4= 26
answer is 72cm multiply 12cm with 6cm
Step-by-step explanation:
multiply length times width
Answer:
A
Step-by-step explanation:
Rectangle:
L x W = area
13 x 9 = 117cm
Triangle:
L x W/2 = area
11 x 5 = 55
55/2 = 27.5
117 + 27.5 = 144.5cm²
Information given:
Eric has 5 blue shirts
Eric has 9 red shirts
First, to find the total ratio, you must add all the shirts together
5+9=14
He has a total of 14 shirts
So the ration for blue shirts to the total is 5:14
The ratio for red shirts is 9:14
As stated, he has 5 blue and 9 red shirts
So the ratio of blue to red is 5:9
