Answer:

$42$ °

Step-by-step explanation:

$A+B+C=180$

all measures of a triangle add up to 180

the angle opposite of angle b on the triangle is $48$ °

$48+90+C=180$

$138+C=180$

$C=42$ °

8^x=2 write down the value of x

Answer:

x = $\frac{1}{3}$

Step-by-step explanation:

Using the rule of exponents

$a^m^{n}$ = $a^{mn}$

Note that 8 = 2³ and 2 = $2^{1}$ , then

$(2^3)^{x}$ = $2^{1}$ , that is

$2^{3x}$ = $2^{1}$

Since the bases on both sides are equal, equate the exponents

3x = 1 ( divide both sides by 3 )

x = $\frac{1}{3}$

Quick! find the solution to the following system x-y=6 x=11 (show all work)

allsm [11]

X - y = 6

Given: x = 11
Find: y

(11) - y = 6
- y = 6 - 11
- y = - 5. (Multiply this entire equation by -1 to make it positive)

y = 5

CHECK
11 - 5 = 6 which is correct so, x = 11 and y = 5

You should all the numbers up, then divide by how many numbers there are. 80.2 would be reasonable. If you want you could round it more.
