In the isosceles triangle ABC
AB=AC
angle B = (3x 32)º
angle C =(87-2x)"
Work out the value
of x.
Answer:
x = 4.5
Step-by-step explanation:
Angle B = angle C because it is an isosceles triangle.
3x32 = 87-2x
96 = 87-2x
reduce:
9 = 2x
x = 4.5
An isosceles triangle is one with two equal-length sides. The value of x is 11.
What is an isosceles triangle?An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.
Since in an isosceles triangle, the angle made by the equal sides and the base are equal, therefore, we can write,
∠B = ∠C
3x + 32 = 87 - 2x
3x + 2x = 87 - 32
5x = 55
x = 11
Hence, the value of x is 11.

Need help with this question
Answer:
C. x = 3
Step-by-step explanation:
8x - 8 = 2x + 10
get the x on it's own
8x - 8 + 8 = 8x
2x + 10 + 8 = 2x + 18
8x = 2x + 18
8x - 2x = 6x
2x + 18 - 2x = 18
6x = 18
now divide each side by 6
6x / 6 = x
18 / 6 = 3
x = 3
X=3
Explanation
8x-8=2x+10
6x=18
x=3

Answer:
x = 25
Step-by-step explanation:
A quadrilateral is inscribed in a circle, so it is a cyclic Quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
3x + 21y = 180°.....(1)
2x + 26y = 180°.....(2)
From equations (1) & (2)
3x + 21 y = 2x + 26y
3x - 2y = 26y - 21y
x = 5y
y = 1/5 x
Plug y = 1/5 x in equation (1)
3x + 21*1/5x = 180
15x + 21x = 180*5
(Multiplying both sides by 5)
36x = 900
x = 900/36
x = 25

Help! brainliest stars and hearts if correct! Please Area and perimeter! Please explain!
Answer:
Perimeter = 14 in
Area = 8 in^2
Step-by-step explanation:
Area = 2x2 + 4x1 = 8 in^2
Perimeter = 2+2+2+2+1+4+1 = 14 in
Answer:
The area is 8 square inches and the perimeter is 16 square inches.
Step-by-step explanation:
First, find the area.
We can find the area of the rectangle at the bottom pretty easily. Since half of the length of the bottom rectangle measures 2 inches, the full length would be 4 inches.
4 ⨯ 1 = 4
So, the area of the bottom rectangle is 4 square inches.
For the square on top, all you have to do is multiply 2 ⨯ 2, because there is no missing length we need to find out.
2 ⨯ 2 = 4
Now, we have to add 4 + 4, because the two quadrilaterals are joined together.
4 + 4 = 8
So, the area of the shape is 8 square inches.
Now, let's find the perimeter. We already know that the bottom rectangle's length is 4 inches, and that the sides are 1 inch tall. The square is 2 inches all around, so, no problems there.
Add the side measurements, not including the 2 inches at the bottom of the square because that side is inside the big shape.
2 + 2 + 2 + 4 + 1 + 4 + 1 = 16
So, the perimeter of the shape is 16 inches.

Audrey measures all 7 pencils in her pencil case and writes the first 6 lengths down.
12.4 cm, 12.6 cm, 13 cm, 13.4 cm, 13.5 cm, 13.3 cm
Audrey calculates the mean length of all 7 pencils to be 13.1 cm.
Find the length of the missing pencil.
cm
[2]
Answer:
the missing pencil length is 13.5 cm
Step-by-step explanation:
The computation of the length of the missing pencil is shown below:
Let us assume the missing pencil be x
Now
(12.4 cm + 12.6 cm + 13 cm + 13.4 cm + 13.5 cm + 13.3 cm + x) ÷ 7 = 13.1 cm
(78.2 cm + x) ÷ 7 = 13.1 cm
78.2 cm + x = 91.7 m
So, x would be
= 91.7 cm - 78.2 cm
= 13.5 cm
hence, the missing pencil length is 13.5 cm
