Answer: 51°F
Step-by-step explanation:
72 - 21 = 51
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:
all real numbers such that x is greater than or equal to 2 (x≥2)
