<u>Answer:</u>

9. x = 12

10. x = 31

<u>Step-by-step explanation:</u>

9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.

7x - 20 = 4x + 16

Solve

3x - 20 = 16

3x = 36

x = 12

Therefore x is equal to 12

<u>Check:</u>

4(12) + 16

= 64

7(12) - 20

= 64

10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:

x + 2x + 25 + 2x = 180

Combine like terms

5x + 25 = 180

Solve

5x = 155

x = 31

Therefore, x = 31.

<u>Check:</u>

31 + 2(31) + 25 + 2(31) = 180

31 + 62 + 25 + 62 = 180

180 = 180

B is 34 mm from the center of circle O, which has radius 16 mm. BP and BR are tangent segments. AC is tangent to O at point Q. F
forsale [732]

Answer:

56.72mm

Step-by-step explanation:

BQ = 34 - 16 = 18mm

Using similar triangle,

AQ = QC =(16*18)/34 = 8.47mm

AC = 2*8.47 = 16.94 mm

Since

BC = AB = sqrt( AQ² + BQ²)

BC = AB = sqrt( 8.47² + 18²)

BC = AB = 19.89mm

Perimeter of triangle ABC = AB + BC + AC

P = 19.89 + 19.89 + 16.94

Perimeter = 56.72mm
