Answer:

B. 94

Step-by-step explanation:

Angle B = 180 - 143 = 37°.

Angle B + Angle C + Angle D = 180°

37° + 49° + Angle D = 180°

Angle D = 180° - 86° = 94°

Alja [10]

Answer:

Sam

Step-by-step explanation:

Sam made a mistake when he said $10^2 -20$ . The steps should have been:

$2n^2-20=2(5)^2-20\\2(25)-20\\50-20=30$

You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.

Find the volume of the triangular prism

juin [17]

Answer:

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

What is the arc length of an arc with radius 15 inches and central angle 30 degrees

RUDIKE [14]

Answer:

7.855 inches

Step-by-step explanation:

The formula to find the length of an arc is :

Arc Length = $\frac{\theta}{360}$ × 2 π r

Here,

Θ ⇒ size of the angle ⇒ 30°

r ⇒ radius ⇒ 15 inches

<u>Let us solve it now.</u>

Arc length = $\frac{\theta}{360}$ × 2 π r

Arc length = $\frac{30}{360}*2*\pi*15$

Arc length = $\frac{30*2*\pi*15}{360}$

Arc length = $\frac{2827.8}{360}$

Arc length = 7.855 inches

Let me know if you have any other questions. :)
