The sum of the measures of two complementary angles is 90°. To put it another way, m∠P + m∠Q = 90°.

So, we can substitute the given values of the angles into this equation.

(52)+(3x+2)=90 \\  \\ 3x+54=90  \\  \\ 3x=36  \\  \\ x=12

Then, to find m∠Q, we plug in 12 for x for the original expression of Q to get 3(12)+2=38.

Dovator [93]

Answer: 1 pound of cheese cost $4.2

Step-by-step explanation:

Nola purchased 2.5 pounds of cheese for 10. $50

Her mother purchased 3 pounds of the same cheese for $12.60

If the cost of the cheese varies directly with the number of pounds purchased, it means that the higher the pounds of cheese purchased, the higher the cost

To determine the the cost of 1 pound of cheese, we wound divide the the cheese by the number of pounds bought.

It becomes 10.5/2.5 = 4.2

CH, DI, and EG are perpendicular bisector of FBJ. Find FJB
Bezzdna [24]

Answer:

<FJB = 112°

Step-by-step explanation:

Sum of 3 angles in a triangle = 180

Given:

<FBJ = 32°

<BFJ = 36°

so

<FBJ  + <BFJ  + <FJB = 180°

32° + 36° +  <FJB = 180°

<FJB + 68° = 180°

<FJB = 180° - 68°

<FJB = 112°
