There is no picture of the quadrilateral so here’s just how to do it find the fourth unknown angle of a quadrilateral, subtract the number of degrees in the other three angles from 360°. Example: How many degrees are in the fourth angle of a quadrilateral whose other angles are 80°, 90°, and 65°?

Find the length of CU, the triangles are similar.

Otrada [13]

Answer:

CU = 117

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{WC}{WU}$ = $\frac{CD}{UV}$

substituting in values to the ratios

$\frac{26}{36x-1}$ = $\frac{24}{132}$ ( cross- multiply )

24(36x - 1) = 3432 ( divide both sides by 24 )

36x - 1 = 143 ( add 1 to both sides )

36x = 144 ( divide both sides by 36 )

x = 4

CU = 36x - 1 - 26 = (36 × 4) - 27 = 144 - 27 = 117

Use f(x)=1/2x and f^-1(x)=2x to solve the problems f^1(-2), f(-4), f(f^-1(-2)?

neonofarm [45]

F^1(-2) = 2(-2) = -4
f(-4) = 1/2 * -4 = -2

f(f^-1(x)) = x so answer is -2

For every 3 you go across you go up 1 so the gradient is rise/run = 1/3

Therefore gradient is 1/3
