<h2>20cm</h2><h2>-------------------------------</h2>
<u>Step-by-step explanation:</u>
sides are 4cm, 8cm, 8cm ----( because isosceles triangle have 2 sides equal )
so, perimeter = sum of all sides
= 4 + 8 + 8
<h3> = 20cm</h3><h2>-------------------------------------</h2><h2>FOLLOW ME</h2>
Short answer = false
Remark
If it is a right triangle, it will obey the Pythagorean Equation. a^2 + b^2 = c^2. Let's see if it does.
Equation
a^2 + b^2= c^2
c must be the longest line. (Hypotenuse)
Givens
a = 24
b = 17
c = 40
Sub and Solve
a^2 + b^2 = c^2
17^2 + 24^2 = c^2 [We'll see if this comes out to 40]
289 + 576 = c^2
865 = c^2 which is no where near what 40^2 equals. 40^2 = 1600
Short answer False
Square root of 865 = (865)^1/2 = 29.4
Answer:
8
Step-by-step explanation:
Answer:
#5 x=8, #6 x=5
Step-by-step explanation:
Theyre vertical so for number 5 you would have the equation
5x+15=55
-15 -15 from both sides
5x=40
divide by 5 from both sides and you get
x=8
Same thing vertical so you would have
16x+7=87
-7 -7 from both sides
16x=80
divide by 16 from both sides
x=5
