Answer:

a = 108°

b = 36°

c = 72°

Step-by-step explanation:

Note : the sum of the interior angles of a regular pentagon = 540°

Then

The measure of one interior angle of a reg pentagon =540/5 = 108°

Therefore a = 108°

c = 180 - 108 = 72°

SRT is a new isosceles triangle then :

$b=\frac{180-108}{2} = \frac{72}{2} =36$

SOLVE OR SIMPLIFY THIS!! -6-(2x+7)=-2(x+6)-1

Oliga [24]

$\\ \sf\longmapsto -6-(2x+7)=-2(x+6)-1$

$\\ \sf\longmapsto -6-2x-7=-2x-12-1$

$\\ \sf\longmapsto -2x-13=-2x-13$

$\\ \sf\longmapsto 2x-2x=0$

$\\ \sf\longmapsto 0$

The hypotenuse is NOT located across from the right angle<br><br> True or false

azamat

The statement, The hypotenuse is NOT located across from the right angle is false.

<h3>What is a right angled triangle? </h3>

A right-angled triangle is a type of triangle that has an angle that measures 90 degrees. The triangle has three sides. The hypotenuse is the longest side of a right-angled triangle. Other sides are the base and the length. The sum of sides in a a right-angled triangle is 180 degrees.

Please find attached an image of a right-angled triangle. To learn more about a triangle, please check: brainly.com/question/9329354

Find the measure of the angle

elena55 [62]

Answer:

? = 113

Step-by-step explanation:

The angles are alternate interior angles. Alternate interior angles are equal if the lines are parallel. Since the lines are parallel, the angles are equal.

? = 113
