Answer:
The answer is none triangle
Step-by-step explanation:
we know that
The sum of internal angles of a triangle must be equal to
In this problem we have three angles, each measuring
so
The total sum of the three angles is equal to
therefore
The answer is none triangle

Answer:
<h2><em><u>4</u></em></h2>
Step-by-step explanation:
![\sqrt[3]{64}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B64%7D%20)
![= \sqrt[3]{4 \times 4 \times 4}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%5B3%5D%7B4%20%5Ctimes%204%20%5Ctimes%204%7D%20)
= <em><u>4</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
C
Step-by-step explanation:
Work backwards. You are given -3 , -30 for C. If you add -3 + 3 and the divide it by 2 , you get 0. If you add 8 + -20 and divide by 2 you get -6 , so the answer is C.
Answer:
3.9%
Step-by-step explanation:
The formula for compound interest to apply is;

where;
A=amount at the end
P=starting amount/principal
n=number of compounding years
t=total number of years
r=interest rate expressed as a decimal
Given
P=$4200, n=2, t=4 and A=$4900 R=?
Substitute values in equation, take r=r

Divide both sides by 4200

Introduce root 8 to the left hand side, thus eliminating the power 8 in the right hand side
![\sqrt[8]{1.1667} =1+0.5r\\\\\\1.0195=1+0.5r\\\\\\1.0195-1=0.5r\\\\\\0.0195=0.5r\\\\\\\frac{0.0195}{0.5} =\frac{0.5r}{0.5} \\\\\\0.039=r](https://tex.z-dn.net/?f=%5Csqrt%5B8%5D%7B1.1667%7D%20%3D1%2B0.5r%5C%5C%5C%5C%5C%5C1.0195%3D1%2B0.5r%5C%5C%5C%5C%5C%5C1.0195-1%3D0.5r%5C%5C%5C%5C%5C%5C0.0195%3D0.5r%5C%5C%5C%5C%5C%5C%5Cfrac%7B0.0195%7D%7B0.5%7D%20%3D%5Cfrac%7B0.5r%7D%7B0.5%7D%20%5C%5C%5C%5C%5C%5C0.039%3Dr)
