You know that the angles in a triangle always add up to 180 degrees, and you know angle a is 35 degrees and angle C is 90 degrees (as indicated by the little square). You must add 90 + 35 which would be 125 degrees,and then subtract 180-125. Basically, for this to be a triangle this last unknown angle must add up with the other two to give you 180, the only possible answer is 55; which would be C

The answer is c. Bcs A + B = 90 [ 35 + 55 = 90]

Answer:

The value of f(x) when x=-1 is 0.5

Therefore $f(-1)=0.5$

Step-by-step explanation:

Given that y=f(x)= $2^x$

to find the f(x) when x=-1 :

That is to find f(-1)

Put x=-1 in the given function f(x)= $2^x$

$f(-1)=2^{-1}$

$=\frac{1}{2}$

$=0.5$

Therefore $f(-1)=0.5$

The value of f(x) when x=-1 is 0.5

6(2x - 11) + 15 = 21

First step use distributive property on the left side to remove the parenthesis, to do this multiply 6 by each term inside the parenthesis:

12x - 66 + 15 = 21

Second step, simplify the left side by combining the like terms:

12x - 51 = 21

Third step, add 51 to both sides of the equation:

12x = 72

Last step, divide both sides by 12:

x = 72/12

x = 6
