Answer:A quadrilateral always has a sum of 360o in total.
Answer:
Angle A = 37 degrees, and Angle B = 53 degrees.
Step-by-step explanation:
We know that this is a right triangle, where angle C is 90 degrees. Since we know the sum of all these angles is 180 in any triangle, we can create an equation.
Angle A = 6x + 7
Angle B = 11x-2
Angle C = 90 degrees
A + B + C = 180
Substitute:
6x + 7 + 11x - 2 + 90 = 180
17x + 5 + 90 = 180
17x + 5 = 90
17x = 85
x = 5
Now substitute 5 for x in both acute angles and you will get your answer.
Angle A = 6(5) + 7
Angle A = 30 + 7
Angle A = 37
Angle B = 11(5) - 2
Angle B = 55 - 2
Angle B = 53
Angle A = 37 degrees, and Angle B = 53 degrees.
Hope this helps.
Answer:
It is 60.
Step-by-step explanation:
When shapes are dilated (when they get bigger or smaller), perimeter changes linearly—in direct proportion with length. This means if the scale factor is 2, then you multiply it by 2. 2 multiplied by 30 equals 60.
(2/9 shirt)/(3 3/5 minute)
= (2/9)/(18/5) shirt/minute
= (2/9)*(5/18) shirt/minute
= 5/81 shirt/minute
5/81 of Brian's shirt is ironed each minute
