Answer:
X = 100
Y= 140
Step-by-step explanation:
The angle of y is same with 140, x u just need to 180= 2(180-140)+x
first we have to find the slope Y2-Y1/ X2- X1
7-(-1)=8
5-(-4)=9 slope= 8/9
Poin slope form ------- Y-Y =M(X-X)
Y+7= 8/9 (X+5) or
Y-1= 8/9 (X-4)
Hi! Let me help you!
Before I answer your question, I should first introduce you to triangles! There ae three triangles: Isosceles triangle, equilateral triangle, and scalene triangle. If I remember it right, isosceles triangles have at least one line of symmetry; an equilater triangle must have three lines of symmetry; a scalene triangle HAS NO line of symmetry.
Now, to answer your question: the answer is FALSE. Scalene triangles have no line of symmetry.
I hope this helped you!

-The area of a circular shape is given by the formula:
We substitute the given value of area in the formula to solve for Radius:
Answer:
x = 28⁰
Step-by-step explanation:
sum of the angles of a triangle = 180⁰
∠A + ∠B + ∠C = 180⁰
∠A = 5x - 60⁰
∠B = 2x + 40⁰
∠C = 3x - 80⁰
<h2>:- Solution</h2>
∠A + ∠B + ∠C = 180⁰
5x - 60 + 2x + 40 + 3x - 80 = 180⁰
5x + 2x + 3x - 60 + 40 - 80 = 180⁰
10x - 20 - 80 = 180⁰
10x - 100 = 180⁰
10x = 180 + 100⁰
10x = 280⁰
x = 280⁰/10
x = 28
