\\ \sf\longmapsto GI^2=FI(IH)

\\ \sf\longmapsto GI^2=6(12)

\\ \sf\longmapsto GI^2=72

\\ \sf\longmapsto GI=\sqrt{72}

\\ \sf\longmapsto GI=8.22

Answer:

\sf\Huge\boxed{C.40}

Step-by-step explanation:

Hello There!

Remember: sum of interior angles of a triangle = 180

so to find x we use this equation

180 = 90 + 7x + 5 + 9x + 5 ( the little square in the triangle indicates that the angle is a right angle. right angles have a measure of 90 so that's where the 90 came from.)

now we solve for x

step 1 combine like terms

90 + 5 + 5 = 100

7x + 9x = 16x

now we have 180 = 16x + 100

step 2 subtract 100 from each side

180 - 100 = 80

100 - 100 cancels out

now we have 80 = 16x

step 3 divide each side by 16

80/16 = 5

16x/16=x

we're left with x = 5

Finally we plug in 5 into x for angle a

7(5)+5

7*5=35

35+5=40

so we can conclude that the measure of angle A is 40 degrees

Answer:

D. 48

Step-by-step explanation:

For (2,12), x is multiplied by 6 to get y.

For (4,28), x is multiplied by 7 to get y.

For (6,y), x should be multiplied by 8 to get y, which would be 48
