These three angles are on a line so must total 180°.
So 180-(52+58)=
180-110=70

So angle q is 70°.

What is the length of the hypotenuse triangle if both sides are 36

vovikov84 [41]

Answer:

<h3> $\boxed{ \bold{ \huge{ \boxed{ \sf{36 \sqrt{2} \: \: units}}}}}$ </h3>

Step-by-step explanation:

Given,

Perpendicular ( P ) = 36

Base ( b ) = 36

Hypotenuse ( h ) = ?

Finding the hypotenuse  :

Using the Pythagoras theorem :

$\sf{ {h}^{2} = {p}^{2} + {b}^{2} }$

plug the values

⇒ $\sf{ {h}^{2} = {36}^{2} + {36}^{2} }$

Evaluate the power

⇒ $\sf{ {h}^{2} = 1296 + 1296}$

Add the numbers

⇒ $\sf{ {h}^{2} = 2592}$

Squaring on both sides

⇒ $\sf{h = 36 \sqrt{2} }$ units

Hope I helped!

Best regards!!

A rectangle has a perimeter of 68 inches it’s length is 2 inches less than 3 times the width what is the area of the rectangle

Kruka [31]

Answer:

225 inches²

Step-by-step explanation:

Let the length be l and width be w

Condition 1

2l+2w=68 (Perimeter=68)--------(i)

Condition 2

l=3w-2 ---------(ii)

Putting equation (ii) in (i)

2(3w-2)+2w=68

6w-4+2w=68

8w-4=68

8w=68+4

8w=72

dividing both sides by 8

w=9 inches

now putting w=9 in (ii)

l=3(9)-2

l=27-2

l=25 inches

Now

Area of rectangle = l × w

=9 × 25

=225 inches²
