Answer:

x = 52 degrees

Step-by-step explanation:

Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as

180 degrees - (x + 72 degrees), or 108 - x degrees.

The three interior angles of the triangle must add up to 180 degrees. Hence

108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:

108 - x + 34 = 90

This yields x = 52 degrees.

Answer:

x = 52

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles of a triangle

x+72 = 34+90

x +72 =124

Subtract 72 from each side

x = 124-72

x =52

40^14 over 4^5 then divide 40 by 4 and 14-5 which would be 10^9

Step-by-step explanation:

i think, im not positive but you multiply the whole numbers and add the exponents then you can simplify the numerator and denominator. but you dont divide the numerator exponets by the 5, you just sutract. if you want i can explain it a lil better in the comments

F(x) = 3 - 2x and g(x) = 1/X+5 what is the value of (f/g)(8)

Nina [5.8K]

Answer:

(f/g)(8) = -104/41

Step-by-step explanation:

Fill in the value for x and do the arithmetic.

f(8) = 3 -2·8 = 3 -16 = -13

g(8) = 1/8 +5 = (1+40)/8 = 41/8

Then the ratio is ...

(f/g)(8) = f(8)/g(8) = -13/(41/8) = -13(8)/41

(f/g)(8) = -104/41
