Answer:
35
Step-by-step explanation:
Since this triangle is a 90 degree angle, all you'd have to do is subtract 55 from 90 and you've got you answer.
Answer:
24
Step-by-step explanation:
You can use the Pythagorean Theorem to solve this:

The legs of the triangle are put into either a or b and the hypotenuse is put into c. In this case, they've already given you the hypotenuse, but now you need to find the leg:

2025 +
= 2601
<em><u>Subtract 2025 from both sides:</u></em>
2025 +
= 2601
-2025 -2025
_____________
= 576
<em><u>Square root:</u></em>

b = 24
Y=5x+7 is the answer i think
Answer:
<u><em>x=9</em></u>.
<em><u>perimeter=68</u></em>
<em><u>area=168</u></em>
Step-by-step explanation:
First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to multiply the length and the width so 28x6 which is <em><u>168</u></em>.
hope that helped :)
