<u>Let's name these angles</u>.
∠ A = 72°
∠ B = 54°
∠ C = 54°
Now, in this triangle, two angles, i.e., ∠ B and ∠ C are same.
According to the properties of triangle, sides opposite to two equal angles in a triangle are also equal, which means the two sides opposite to 54° in the figure will be equal.
=> <u>AB = AC</u>
Now, if there are two equal sides in a triangle then the triangle is called <u>Isosceles Triangle.</u>
So, the above triangle is an <u>Isosceles Triangle</u>.
Answer:
c < - 4
Step-by-step explanation:
- 4c - 1 > 15 ( add 1 to both sides )
- 4c > 16
Divide both sides by - 4 , reversing the symbol as a result of dividing by a negative quantity.
c < - 4
B) Radius
Diameter is from side to side
Circumference is around the circle
Tangent is a line that touches another line without crossing
In the coordinate plane, quadrilateral ABCD has vertices A(-2, 3), B(4,5), C(10, -1), and D(8, -9). Let E, F, G, and H

Answer:
G(3, 1), H(2, 3)
Step-by-step explanation:
When D is the midpoint of EG, it means ...
D = (E + G)/2
or
G = 2D -E = 2(3,4) -(3,7) = (2·3-3, 2·4-7) = (3, 1)
Likewise, H is ...
H = 2D -F = 2(3,4) -(4,5) = (2·3-4, 2·4-5) = (2, 3)
not my answer but i hope it helps you.
It’s a little surprising that this question didn’t come up earlier. Unfortunately, there’s no intuitive way to understand why “the energy of the rest mass of an object is equal to the rest mass times the speed of light squared” (E=MC2). A complete derivation/proof includes a fair chunk of math (in the second half of this post), a decent understanding of relativity, and (most important) experimental verification.
