In a triangle , angle B is half of angle A. Angle C is 5 more than double angle A. What are the measurements of each angle?

zysi [14]

$x=m\angle A\\\\\dfrac{1}{2}x=m\angle B\\\\2x+5=m\angle C$

$\text{We know: the sum of measures of the angles in the triangle}\\\text{is equal}\ 180^o$

$\text{Therefore we have equation}\\\\m\angle A+m\angle B+m\angle C=180^o\\\\x+\dfrac{1}{2}x+2x+5=180\ \ \ \ |-5\\\\3\dfrac{1}{2}x=175\\\\3.5x=175\ \ \ \ |:3.5\\\\\boxed{x=50}$

$m\angle A=50^o\\\\m\angle B=\dfrac{1}{2}\cdot50^o=25^o\\\\m\angle C=2\cdot50^o+5=105^o$

Select the correct answer. Which expression has a greatest common factor of 3h? A. 18h2 − 6h B. 3 − 9h C. 6h2 − 2h D. 12h + 21h2

horsena [70]

Answer: D. 12h + 21h2

Step-by-step explanation: The answer is D,

because when you devide 12h/3h = 4

and for the other value 21h2/3h=7h

4 + 7h

if you perform the same operation with the rest of answers you will get a minor values if you compare with this results, because of that the answer with the greatest common factor is D.

Blizzard [7]

Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough
