Answer:
m∠Q ≈ 53°
Step-by-step explanation:
To find the measure of ∠Q, the law of cosines will need to be used. Lowercase letters represent the side lengths, while upper case letters represent angles.
In this situation, 'A' will be ∠Q. Therefore:
17² = 18² + 20² -2(18)(20)cosQ
Simplify:
289 = 324 + 400 -2(360)cosQ
Continue simplifying down:
-435 = -720cosQ
Divide both sides by '-720':
0.604 = cosQ
m∠Q ≈ 52.83 or 53° rounded to the nearest whole degree.
Answer:
≈ 6.16
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(5, - 5) and (x₂, y₂ ) = D(7, 3)
d = √ (7 - 5)² + (3 + 5)²
= √ 2² + 8² = √ 4 + 64 = √68 ≈ 6.16 ( to 2 dec. places )
Answer: 33.5
Step-by-step explanation: this question is on brainly lol but nobody explained it
1865 - 1240 = 625
Divide 625 by 1865 (626 goes first)
The answer is 0.335 move the decimal 2x forward
33.5
Answer:
12
Step-by-step explanation:
A square side is twice of the radius
sq side: 4 x 2
sq side: 8
find the area of the square.
A = b x h
A = (8) x (8)
A = 64
<em>Area of square is 64</em>
----------------------------------------------------------------------------------------------------------------
Find the area of the circle
Area of circle:
A = πr²
A = π(4)²
A = 16π
A = 16(3.14)
A = 50.24
----------------------------------------------------------------------------------------------------------------
Divide the circle from the total
50.24/64
50.24/64 = 0.785
0.785 = 78.5/100 = 78.5%
----------------------------------------------------------------------------------------------------------------
Subtract the circle's percentage from 100% (the total)
100 - 78.5 = 21.5
21.5% is your chance of not hitting a point in the circle.
-----------------------------------------------------------------------------------------------------------------
21.5%, or (B), is your answer
-----------------------------------------------------------------------------------------------------------------
hope this helps
