Answer:
x = 19.
Step-by-step explanation:
By the tangent - secant theorem:
BD^2 = AB * EB
so:
8^2 = (x - 7 + 4) * 4
4(x - 3) = 64
4x - 12 = 64
4x = 64 + 12 = 76
x = 76/4
= 19.
4y=-x-12
y=-1/4x-3
so slope is -1/4 and y intercept is negative three

Answer:
A. 5x° + (2x + 7)° = 90°
Step-by-step explanation:
Complementary angles add up to give us 90°.
From the given diagram, we have a part of the angles on a straight line as a right angle. Which means it is 90°. Therefore, the other two angles, 5x° and (2x + 7)° will add up to give us 90°. Thus, 5x° and (2x + 7)° are complementary angles.
Therefore:
5x° + (2x + 7)° = 90°
11. 6÷5=$1.2 12. 50÷7.90= $6.32 13. 24÷2.95= $8.13 14. 200÷12=$16.6 15. 14.40÷4.5= $3.2 or (4.5÷14.4= 0.3125- Probably not the right answer, I just know it. :)) 16. 22÷2 = $8. Here are your answers! I hope they are right. :)
