Formula for area of a triangle :

<u><em>Area (triangle) = 1/2 × base × height</em></u>

<u><em /></u>

=============================================================

Solving :

<u>Triangle 1 (Top Left)</u>

⇒ Area = 1/2 × 11 × 3

⇒ Area = 33/2

⇒ Area = 16.5 in²

<u>Triangle 2 (Top Right)</u>

⇒ Area = 1/2 × 8 × 7.2

⇒ Area = 4 × 7.2

⇒ Area = 28.8 cm²

<u>Triangle 3 (Bottom Left)</u>

⇒ Area = 1/2 × (5.5 + 5) × 10.4

⇒ Area = 10.5 × 10.4

⇒ Area = 109.2 m²

<u>Triangle 4 (Bottom Right)</u>

⇒ Area = 1/2 × (2 + 7) × 5.5

⇒ Area =  9 × 2.75

⇒ Area = 24.75 in²

Find the radius of the sphere with the given volume<br><br>volume= 9/16 (pie symbol)ft cubed
xz_007 [3.2K]
Remember, the volume formula of a sphere is \frac{4}{3}  \pi  r^{3}.

Set that equation equal to whatever volume they give you and solve for r.

\frac{4}{3} \pi r^{3} = \frac{9}{16} \pi

Now solve for r! I know you can do this. If you need help, just comment.

19. Find the value of X (In the picture) (giving points to best answer/brainlest)​
Tema [17]

Answer:

x = 61 degrees

Step-by-step explanation:

The triangle on the right is isosceles and the base angles are congruent

the sum of the inner angles of a triangle is 180 degrees

2 * 74 + y = 180

148 + y = 180

y = 32 degrees

the total angle is 90 degrees

so we have that

90 - 32 = 58 degrees

Also the left triangle is isosceles, so we have

2x + 58 = 180

2x = 122

x = 61 degrees
