Prove: m∠A=72°
Answers
Answer:
Step-by-step explanation:
By the triangle sum theorem, the sum of angles in a triangle is equal to 180°. Therefore, m∠A + m∠B + m∠C = 180°. Using the Substitution property
(6x)° + 90° + (x+6)° = 180°
To solve for x, first combine the terms to get (7x + 96) = 180°
Using the Subtraction property of equality,
7x = 84.
Then using the division property of equality x = 12.
To find the measure of angle A,
Use the subtraction property to get m∠A = 6(12)°.
Finally simplifying the expression gets m∠A = 72°.

10. V = ¹/₃πr²h
V = ¹/₃(3.14)(6)²(10)
V = ¹/₃(3.14)(36)(10)
V = ¹/₃(3.14)(360)
V = ¹/₃(1130.4)
V = 376.8 cm³
The answer is C.
11. V = ¹/₃πr²h
V = ¹/₃(3.14)(6)²(10)
V = ¹/₃(3.14)(36)(10)
V = ¹/₃(3.14)(360)
V = ¹/₃(1130.4)
V = 376.8 cm³
The answer is C.
12. V = 1¹/₃πr³
V = 1¹/₃(3.14)(3)³
V = 1¹/₃(3.14)(27)
V = 1¹/₃(84.78)
V = 113.04 cm³
The answer is C.
13. V = 1¹/₃πr³
V = 1¹/₃(3.14)(12)³
V = 1¹/₃(3.14)(1728)
V = 1¹/₃(5425.92)
V = 7234.56 cm³
The answer is A.
14. S = 4πr²
324π = 4(3.14)(r)²

12.56 12.56
81 = r²
9 = r
V = 1¹/₃πr³
V = 1¹/₃(3.14)(9)³
V = 1¹/₃(3.14)(729)
V = 1¹/₃(2289.06)
V = 3052.08

Answer:
8a+1=33
Step-by-step explanation:
you can solve 3a-2=10 by simplifying to 3a=12, so a=4. Then you replace the a in 8a+1 with 4 to get 32+1, which is 33
Answer:
33
Step-by-step explanation:
3a-2= 10
3a=12
a=4
in this equation a=4 so you substitute that value into the other equation
8(4) +1=33
Answers
4=a/4
Then, multiply both sides by 4 in order to get the 4 on the right to cancel out of the denominator:
16=a
