Flura [38]

Answer:

Angle, $\theta=70.4^{\circ}$

Step-by-step explanation:

We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.

The attached figure shows the A frame. Let $\theta$ is the angle that the roof makes with the floor. So,

$\tan\theta=\dfrac{45}{16}\\\\\tan\theta=2.81\\\\\theta=\tan^{-1}(2.81)\\\\\theta=70.4^{\circ}$

So, the angle of 70.4 degrees is the angle that the roof makes with the floor.

Triangle ABC is an obtuse triangle with the obtuse angle at vertex B. Angle A must be

wlad13 [49]

We have to find the correct statement for angle A in a triangle ABC, which is an obtuse triangle. We know that angle B is obtuse ( greater than 90 degrees ). Therefore angles A and C must be less than 90 degrees. Angle A can not be congruent to angle B ( angle B > angle A ). It can be congruent to angle C but just in case that ABC is an isosceles obtuse triangle. Answer: Angle A must be A ) less than 90 degrees.

Ill give BRAINLIEST if right! pls help!

Answer:

$36\:\text{units}$

Step-by-step explanation:

Drop a height directly through the middle of the triangle, intersecting the base at a 90 degree angle. We form two right triangles and can use the Pythagorean theorem to solve for the hypotenuse.

The Pythagorean theorem states that for any right triangle, the following is true:

$a^2+b^2=c^2$ , where $a$ and $b$ are two legs of the triangle and $c$ is the hypotenuse.

Therefore, we have the following equation (using the graph to measure the length of the two legs):

$5^2+12^2=x^2,\\x^2=169,\\x=13$

The other "tilted" side must be the same length. The base of the triangle can be measured using the graph - 10 units.

Therefore, the perimeter is $10+13+13=\boxed{36\:\text{units}}$
