Write an equation that could be used to find the measure of angle A
Ainat [17]

Answer: C

Step-by-step explanation: The numerator is the angle measure, and the denominator is the side length. For angle B, the angle is 47 degrees. The opposite side is b, which is 85. We are finding the angle A, which is the numerator. The side 94 is opposite of angle A.

PLEASSS HELP!!!!!!! I REALLY NEED HELP!!
loris [4]

Answer:

\underline{ \boxed{x = 11} } \\ \underline{ \boxed{ABE = 55}}

Step-by-step explanation:

if \: the \: question \: is \to \\  \overline{AZ} \: \perp \: \overline{CD}, \: m \angle{ABE} = 5x, \\ and  \\ \: m \angle{EBD } = 3x + 2\\ but \: m \angle{EBD }  +  m \angle{ABE} = 90 \\ hence \to \\ (3x + 2) + (5x) = 90 \\ 8x + 2 = 90 \\ 8x = 90 - 2 \\ 8x = 88 \\ x =  \frac{88}{8}  \\ \boxed{ x = 11} \\  \\ if \: x = 11, \: then \to \\ m \angle{ABE} = \: 5x = 5(11) \\  \boxed{m\angle{ABE} =55}

For real answers 25 pts and a mark!! Help please!!Suppose that there are two types of tickets to a show: advance and same-day. A
Diano4ka-milaya [45]

Answer: 35 advance, 30 same day

Step-by-step explanation:

$35 * A + $15 * S = $1675

A + S = 65 So. A = 65 - S

Plug in for A:

35(65-S) + 15S = 1675

2275 - 35S + 15S = 1675

-20S = -600

S = 30 same day tix

A = 35 advance tix

If x is not equal to 0 then u/x + 5u/x - u/5x = what?
gavmur [86]
\frac{u}{x}+\frac{5u}{x}-\frac{u}{5x}=\frac{5u}{5x}+\frac{25u}{5x}-\frac{u}{5x}=\frac{5u+25u-u}{5x}=\frac{29u}{5x}
