Find the measure of the largest angle in the triangle

tester [92]

Answer:

72°

Step-by-step explanation:

Find the image of the question attached

The sum of angle in a triangle is 180°

Hence:

15x+24x+21x = 180°

60x =180

x =180/60

x= 3

Get the largest angle

The largest angle out of the angles is 24x

24x =24(3)

24(3) =72°

Hence the measure of the largest angle is 72°

I need help on this logarithmic equation I need it solved step by step * It asks to solve it in terms of x. *

Rashid [163]

To solve the function in terms of x:

$\log _{4^x}2^a=3$

find the power of the subscripts of the log

$\begin{gathered} \log _{4^x}2^a=3 \\ \log _{2^{2x}}2^a=3 \\ \frac{a}{2x}\log _22=3 \\ \text{where }\log _22=1 \\ \frac{a}{2x}=3 \end{gathered}$

cross multiply the expression

$\begin{gathered} \frac{a}{2x}=3 \\ a=3(2x) \\ a=6x \end{gathered}$

Therefore the correct answer of a = 6x

Evaluate the following expression when b = -4 , -4.5b=

Elza [17]

Answer:

Step-by-step explanation:

The question is asking you to evaluate -4.5b, which is a simplified way of saying

-4.5 * b

Since we know that b = -4, we can insert that instead of b.

-4.5 * -4

The two negatives cancel each other out, so you're left with

4.5 * 4 = 18

Driving 70 mph, it takes Alicia 2 hours to reach the airport to go on a vacation. It then takes her 2 hours to get to her destin

OLga [1]

She drove 2 hours at 70 miles per hour, so she drove 70 * 2 = 140 miles total.

The jet traveled 400 miles per hour for 2 hours for a total of 400 * 2 = 800 miles.

Total miles = 140 + 800 = 940 miles.

The answer is C.
