The measures of three angles of a triangle are given by (8x - 5), (2x)º, and (3x – 10). What is the measure of the largest angle? A 15° B 115° C. 35° D 150°
Answer: 115°
Step-by-step explanation:
We should note that the sum of the angles that are in a triangle is equal to 180°, therefore we will add the angles given and equate them to 180°. This will be:
(8x - 5) + (2x) + (3x - 10) = 180
8x - 5 + 2x + 3x - 10 = 180
Collect like terms
8x + 2x + 3x = 180 + 5 + 10
13x = 195
x = 195/13
x = 15
The angles are:
8x - 5 = 8(15) - 5 = 120 - 5 = 115°
2x = 2(15) = 30°
3x - 10 = 3(15) - 10 = 45 - 10 = 35°
Therefore, the largest angle is 115°
Can somebody plz help answer these math questions correctly thx (only if u done this before) :3
WILL MARK BRAINLIEST WHOEVER ANSWERS THESE FIRST!!!
Answer:
Step-by-step explanation:
The sum of complementary angles equals to 90° while the sum of supplementary angles equals 180°.
The measure of the complementary angles will be:
19. 42°
= 90° - 42°
= 48°
20. 78°
= 90° - 78°
= 12°
21. 32°
= 90° - 32°
= 58°
22. 72°
= 90° - 72°
= 18°
22. 40°
= 90° - 40°
= 50°
23. 14°
= 90° - 14°
= 76°
The measure of the supplementary angles will be:
25. 36°
= 180° - 36°
= 144°
26. 124°
= 180° - 124°
= 56°
27. 85°
= 180° - 85°
= 95°
28. 84°
= 180° - 84°
= 96°
29. 153°
= 180° - 153°
= 27°
30. 176°
= 180° - 176°
= 4°
Note that the value of the complementary angles were gotten by deducting the angles given from 90° while the supplementary angles were gotten by deducting the values given from 180°.

6. A manufacturer uses a mold to make a part in the shape of a triangular prism. The dimensions (1 point)
of this part are shown below.
Calculate the volume of the part. Round your answer to the nearest whole number.
A 108 mm
B 217 mm
C 454 mm
D 880 mm
Pls show work I really need help
Answer:
A 108 mm
Step-by-step explanation:
The computation is shown below:
As we know that
V = Bh
where
B denotes the area of the base
and h denotes the height of the prism.
Now
V = (1 ÷ 2 × 12.6 × 1.6) × 10.75
= 108.36 mm
= 108 mm
Hence, the option a is correct

Answer:
48
Step-by-step explanation:
Answer: The missing side is 48
Step-by-step explanation: The missing side is 48 because in this case, you got to do length time width, So the length is 6 and the width is 8, so now you multiply, which would be 6 times 8 is 48.
6 x 8 = 48

Andy buys a new car for $23,540. He estimates that the car will decrease in value by about 5% each year. Which of the following functions best models this situation?
Answer: y=0.05x-23540
Step-by-step explanation: We turn 5% into a decimal which is 0.05 and we add x to it so we can pick how many years. Then we subtract 23540 because he has used that money to buy the car.
QR is a radius of circle R and PQ is tangent to circle R. Find the value of x.
Answer:
x = 13
Step-by-step explanation:
using the Pythagorean theorem
x² = 85² - 84²
x² = 7225 - 7056 = 169
x = 13
Answer:
x = √(85²-84²)
x = √(7225-7056)
x = √169

What is the measure of x?
Answer:
Step-by-step explanation:
52+x=90
x=38
Answer:
x=38 degrees
Step-by-step explanation:
You know that x degree angle plus 52 degree angle have to equal 90 degrees. Therefore, the equation is x+52=90. You want to isolate x so you have to subtract 52 from both sides. The equation will look like x=90-52. Simplify this to get x=38. Therefore, x= 38 degrees.

Ai Mi went to the store to buy some chicken. The price per pound of the chicken is $3.50 per pound and she has a coupon for $2.50 off the final amount. With the coupon, how much would Ai Mi have to pay to buy 3 pounds of chicken? Also, write an expression for the cost to buy pp pounds of chicken, assuming at least one pound is purchased.
Answer:
$8 for 3 pounds
cost for p pounds: 3.50p - 2.50
Step-by-step explanation:
Cost of 3 pounds:
Original cost = Cost per pound x 3
= 3.50 x 3
= 10.50
Coupon = 2.50
Final cost = Original cost - Coupon
= 10.50 - 2.50
= $8
Cost of p pounds:
Original cost = Cost per pound x p
= 3.50 x p
= 3.50p
Coupon = 2.50
Final Cost = Original Cost - Coupon
= 3.50p - 2.50
Ai Mi has to pay $8 to buy 3 pounds of chicken. An expression for the cost to buy p pounds of chicken would be; 3.50p - 2.50
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
The Cost of 3 pounds:
Thus Original cost = Cost per pound x 3
= 3.50 x 3
= 10.50
Also, we know that the Coupon cost is 2.50
The Final cost = Original cost - Coupon
= 10.50 - 2.50
= $8
Now Let the Cost of pounds is p
The Original cost = Cost per pound x p
= 3.50 x p
= 3.50p
Also the cost of the Coupon = 2.50
The Final Cost = Original Cost - Coupon
= 3.50p - 2.50
Hence, Ai Mi has to pay $8 to buy 3 pounds of chicken. An expression for the cost to buy p pounds of chicken would be; 3.50p - 2.50
