I don’t know how to solve this

Romashka-Z-Leto [24]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the length of all the sides in the figure.

The arc of the semi- circle is included in this.

length of arc = $\frac{1}{2}$ πd ← d is the diameter

here d = 8, hence

arc = $\frac{1}{2}$ π × 8 = 4π ← exact length

Perimeter = 10 + 8 + 10 + 4π ≈ 40.57 in ( nearest hundredth )

Is anyone here in connections academy geometry. even if your not can someone help me with the question in the images. If correct

Answer:

$13.05cm^2$

Step-by-step explanation:

Area of a triangle is given a half the product of base by the perpendicular height:

$A=0.5bh$

Given h=9cm, and b=2.9cm, the area is calculated as:

$A=0.5bh\\\\A=0.5\times 2.9cm \times 9cm\\\\A=13.05cm^2\\$

Hence, area of the triangle is 13.05 sq cm

What is length of BC ?

MAXImum [283]

Answer:

BC = 10

Step-by-step explanation:

Since this is an isosceles triangle

AC = BC

3x-5 = 2x

Subtract 3x from each side

3x-5-3x = 2x-3x

-5 = -x

Multiply each side by -1

5 =x

BC = 2x

=2 *5

BC =10
