Answer:

114

Step-by-step explanation:

following order of operations, we have to do parenthesis first

9 x (8+5) - 3=

9 x 13 - 3

since we have no exponents, we multiply next

117-3

finally, we subtract and get our answer

Answer:

it is 114

Step-by-step explanation:

you do distributive property and since there’s no number it counts as a 1 so then you had 8+5 and you get 13 then you times that by 9 then subtract that answer with 3.

Answer:

x=43

Step-by-step explanation:

A triangle contains 180

82+55+x=180

=>137+x=180

=>x=180-137

Therefore, x=43 (you can use therefore sign instead of therefore)

The equation sin(25") = 9/c

Marizza181 [45]

Option B: 21.3 in is the length of AB

Explanation:

The equation is $\sin 25^{\circ}=\frac{9}{c}$

To find the length of AB, let us equate,

$c=\frac{9}{\sin 25^{\circ}}$

Substituting the value for sin 25°, we get,

$c=\frac{9}{0.4226}}$

Dividing the values, we have

$c=21.3$

Thus, the length of AB is 21.3 in.

The correct answer is Option B.
