Answer:
4:3
Step-by-step explanation:
You divide 8 and 6 by 2 to simplify it
Step-by-step explanation:
A triangle's angles add up to be 180 degrees, so you can create an equation to be 180= 130+5x. (the 5x is 2x + 3x)
subtract 130 from both sides and get 50=5x, divide both sides by 5, x is equal to 10.
I'm not sure which angle is angle a, but if you substitute x with 10, you can find the measure of the angle, so if it's 2x, 2(10)=20 and if 3x, 3(10)=30
Answer:
12 inches
Step-by-step explanation:
21 feet = 3 inches (in a model)
84 feet = 12 inches (in a model)
84 ÷ 21 = 4
3 × 4 = 12
