Solve for x for both and show how you got the answer (WILL MARK BRAINLIEST)

1.) 9.32

2.) 4.82

Step-by-step explanation:

neat trick i learned that really helps: SOH-CAH-TOA

Sine (opposite, hypotenuse), Cosine (Adjacent, Hypotenuse), Tangent (Opposite, Adjacent)

1.)

sin(21) = x/26    < multiply by 26 to get x by itself

26*sin(21) = x  < multiply 26 by sin(21)

9.32 = x      < rounded answer

2.)

cos(64) = x/11      < multiply by 11 to get x by itself

11*cos(64) = x      < multiply 11 by cos(64)

4.82 = x      < rounded answer

2 5/8 is the final answer! : )

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
