Please help me with these will give Brain

1. EH = 13, 2. x = 70

Step-by-step explanation:

1. Since the triangle here is a right triangle, you can use the Pythagorean theorem: a^2 + b^2 = c^2 (where c is EH, a is BE, and b is BH)

plug in the numbers to get: EH^2 = 5^2 + 12^2

work it out: EH^2 = 25 + 144 = 169

take the square root of each side: EH = 13

2. I'm not exactly sure how to explain this one, but I just took the average of the two angles (112 and 28) and got 70 degrees.

Since x corresponds to the 112 angle on the one side and 28 angle on the other side, I figured that if you move the cross in the middle to where it's at the circle's center, the x angle would equal the new 112 and 28 angles. So I got the average of those two and it was 70.

You'll just have to trust me on this one lol.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
