Answer:

C (86.113)

Step-by-step explanation:

First, find the missing angle B. Since angles in a triangle add upp to 180,

180-26-90= 64

Then use the formula a/<em>sin</em>a = b/sinb

' a' in the formula is the missing length X and sina is the corresponding(opposite) angle of X which is sin64.

B in the formula would be 42 and sinb is sin26 (the angle).

Substitute all values into the formula,

X/sin64 = 42/ sin26

Shift sin64 to the right side:

X= 42(sin64)/ sin26

X= 86.113

Hope this makes sense:)

Step-by-step explanation:

\tan(26)  =  \frac{42}{x}  \\0.487732588565 \times x = 42 \\ x  = 86.11276134633

<em><u>C.x=86.113</u></em>

Answer:

A=23512.32

Step-by-step explanation:

The equation for the area of a cylinder is A=2πrh+2πr^2

If we substitute the radius and height, the equation would be A=2π(60)(2.4)+2π(60)^2

π can be shortened to 3.14 so it's A=2(3.14)(60)(2.4)+2(3.14)(60)^2

We're left with 904.32+22608

So the answer is 23512.32

Solve 2 log x = log 64. (1 point)
Vladimir79 [104]

Answer:

8

Step-by-step explanation:

2log(x)=log(64)

By logarithms properties

xlog_{a}(b)=log_{a}(b^{x} )  \\

log(x²)=log(64)

When you have log or ln in both sites, you delete them and...

x²=64

\sqrt[]{x^{2} } =\sqrt{64} \\x=8
