If line AB = 3 centimeters, and line BC = 4 centimeters, which does line AC equal?

1 answer:

7 0

This is a standard Pythagorean value triangle of 3,4,5

AC=sqrt(3^2+4^2)= 5

So the hypotenuse AC is 5cm long so the answer is C

∠A and \angle B∠B are supplementary angles. If m\angle A=(x-16)^{\circ}∠A=(x−16) ∘ and m\angle B=(3x+28)^{\circ}∠B=(3x+28) ∘ , t

Answer:

∠A = 26°

Step-by-step explanation:

Supplementary angles total 180°.

∠A +∠B = 180°

(x -16)° +(3x +28)° = 180°

4x° + 12° = 180°

x° +3° = 45°

x° = 42°

∠A = (x -16)° = 42° -16°

∠A = 26°

A ladder is leaning against a vertical wall. The distance from the top of the ladder to the base of the wall is 17 feet. The dis

Gennadij [26K]

Answer:

18.4 feet

Step-by-step explanation:

-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.

-let the ladder be C, the wall be a, the base to the bottom be b.

-substitude into the equation, which will leave us with:

C^2 = 17^2 + 7^2

C^2 = 289 + 49

C^2 = 338

C = square root of 338, which is 18.4 feet!
