Answer 1

Answer:

x = 22.62°  (nearest hundredth)

Step-by-step explanation:

As this is a right triangle, we can use the cosine trigonometric ratio to find x.

$\sf \cos(\theta)=\dfrac{A}{H}$

where:

• $\theta$ is the angle
• A is the side adjacent the angle
• H is the hypotenuse (the side opposite the right angle)

Given:

• $\theta=x$
• A = 12
• H = 13

Substitute the given values into the formula and solve for x:

$\implies \cos(x)=\dfrac{12}{13}$

$\implies x=\cos^{-1}\left(\dfrac{12}{13}\right)$

$\implies x=22.61986495...^{\circ}$

$\implies x=22.62^{\circ}\:\: \sf(nearest\:hundredth)$

Answer 2

Answer:

45 degrees

Step-by-step explanation:

so we know there is one 90 degree angle

and the other two angles are congruent

so the math would go like this

180-90=90

90/2= 45

(the 2 represents the two angles)
