Answer:
x = 16
Step-by-step explanation:
SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.
The angles opposite to equal sides are equal.
⇒ ∠STR = ∠R
∠STR = 4x - 28
Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair
∠STR + ∠STU = 180° {linear pair}
4x - 28 + 9x = 180
4x + 9x - 28 = 180 {Combine like terms}
13x- 28 = 180
Add 28 to both the sides
13x = 180 + 28
13x = 208
Divide both sides by 13
x = 208/13
Answer:
Yes
Step-by-step explanation:
a^2+b^2=c^2 is for right triangle so
6^2+8^2=10^2
36+64=100
100=100
so it's a right triangle
Answer:
132un^2
or 132 units squared
Step-by-step explanation:
I'm going to solve for the areas of all three shapes separately and then add them together.
Triangle 1:
6 * 8 * 0.5 =
24
Rectangle:
12 * 8 =
96
Triangle 2:
8 * 3 * 0.5 =
12
All of them together:
24 + 96 + 12 =
132
Answer:
Step-by-step explanation:
To find the value of x, using Pythagorean theorem.
x² = 6² + 4²
= 36 + 16
= 52
= 2*2*13
x = √2*2*13
x = 2√13
