Answer:
The angles across from the legs are called base angles
Step-by-step explanation:
we know that
The isosceles triangle is a triangle with two equal angles and two equal sides
The two equal sides are called legs and the third side is called base
The two equal angles are called base angles and the third angle is called vertex angle
Answer: n = -6
Step-by-step explanation:
2(n+5) = -2
2n + 10 = -2
Now, subtract 10 from both sides.
2n + 10 - 10 = -2 - 10
2n = -12
Now, divide by 2 on both sides.
2n/2 = -12/2
n = -6
Answer:
P = 60 cm
Step-by-step explanation:
To solve this question we will use the property of the tangents drawn from a point to a circle.
"Length of tangents drawn from a point to a circle are equal in measure."
By this property,
Therefore, BG ≅ FB ≅ 7.5 cm
AG ≅ AH ≅ 6.5 cm
CF ≅ EC ≅ 8.5 cm
Since m∠B ≅ m∠D
Therefore, length of tangents FB ≅ GB ≅ DE ≅ DH ≅ 7.5 cm
Since, Perimeter of ABCD = AB + BC + CD + DA
AB = 7.5 + 6.5 = 14 cm
BC = 7.5 + 8.5 = 16 cm
CD = 8.5 + 7.5 = 16 cm
DA = 7.5 + 6.5 = 14 cm
Now Perimeter = 16 + 16 + 14 + 14 = 60 cm
Therefore, P = 60 cm will be the answer.

Answer:
<h2>9(2n + 1) = 18n + 9</h2>
Step-by-step explanation:
9(2n + 1)
<em>use the distributive property a(b + c) = ab + ac</em>
= (9)(2n) + (9)(1) = 18n + 9
