How do you find the size of angle B?

Mathematics
1 answer:
Vitek1552 [10]3 years ago

the sum of the interior angles is 180° (triangles)

it's isosceles, 2 equal sides and 2 equal angles.

you take away the given angle from 360° and you will find the sum of the 2 equal sides, you divide by 2 and you have the angle b (equal to angle C).


(180 - 72) : 2  =

108 : 2 = 54° (your answer)

-----------------------

72 + 54 + 54 = 180°

The answer is good.

You are driving home on a weekend from school at 55 mi/h for 110 miles. it then starts to snow and you slow to 35 mi/h. you arri
stepladder [879]

Okay lets get started.

I drove 110 miles with speed of 55 mi/hr so the time taken =

time = distance / speed

time = 110 / 55 = 2 hrs For the distance which is covered with 55 mi/hr speed.

Total time for reaching home is 4 hrs 15 minutes. (given in question)

Means rest distance after snow is covered in = 4 hrs 15 minutes - 2 hrs

= 2 hrs 15 minutes = 2 + 15/60 = 2.25 hrs

The speed in snow driving is 35 mi/hr

So distance covered in snow driving is = 2.25 * 35 = 78.75 miles

Hence the total distance = 110 + 78.75 = 188.75 miles : Answer

Hope that will help :)

Answer:

see explanation

Step-by-step explanation:

A

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then

A = π × 6² = 3.14 × 36 = 113.04 m²

B

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here C = 28.26 , then

2πr = 28.26 ( divide both sides by 2π )

r = \frac{28.26}{2(3.14)} = \frac{28.26}{6.28} = 4.5 in
