Answer:

∠4 = 45°

Step-by-step explanation:

Angles 1, 2, and 4 are all congruent.

∠4 = ∠2

x +30 = 2x +15

15 = x . . . . . . . . . . . . . subtract x+15

x + 30 = 45 = ∠4

H(y)=9/5 • 2y at y=-2

Deffense [45]

Answer:

$H( - 2) = - 7 \frac{1}{5}$

Step-by-step explanation:

We want to evaluate the equation

$H(y) = \frac{9}{5} \times 2y$

at y=-2

We just have to substitute to obtain;

$H( - 2) = \frac{9}{5} \times 2 \times - 2$

We now multiply to get:

$H( - 2) = \frac{9}{5} \times - 4$

This is the same as:

$H( - 2) = \frac{9}{5} \times \frac{ - 4}{1}$

We multiply the numerators separately and denominators separately to get:

$H( - 2) = \frac{9 \times - 4}{5 \times 1}$

$H( - 2) = \frac{ - 36}{5}$

This implies that

$H( - 2) = - 7 \frac{1}{5}$

PLZ HELP!!! CORRECT ANSWER ONLY PLEASE<br><br> What is the value of x?

irina1246 [14]

Answer:

x = 98 mm

Step-by-step explanation:

The angle bisector YT divides the triangle into proportional segments:

VY/VT = KY/KT

Filling in the numbers and multiplying by VT, we have ...

VY/57 = 68/129.2

VY = 57·68/129.2 = 30

Then we can find x from ...

x = VY + YK = 30 +68 = 98 . . . mm

The value of x is 98 mm.
