Answer:

They are vertical angles

x = 5

The mesure of the angles are 35, 35, 145, and 145

Step-by-step explanation:

vertical angles are derectly acrost from each other.

the equations 3x+20 and 10x-15, put into the equation 3x+20=10x-15 will solve for x.

20 = 10x − 15 − 3x

20 = 7x - 15

20 + 15 = 7x

35 = 7x

35/7 = x

5 = x

x = 5

The equations solved are 3 x 5 + 20 = 35 and 10 x 5 - 15 = 35

The sum of all the angles is 360, therefore 35 + 35 = 70

360 - 70 = 290

290/2 = 145

The last two angles are 145 degrees

What is the distance between the points (1, -4) and (1, 0)

tino4ka555 [31]

For this case we have that the distance between two points is given by:

$d = \sqrt{(y2-y1)^2+(x2-x1)^2}$

Given the points:

$(x1, y1) = (1, -4)(x2, y2) = (1,0)$

We substitute in the formula:

$d = \sqrt{(0 - (- 4)) ^ 2 + (1-1) ^ 2}$

$d = \sqrt{(4 ^ 2 + 0 ^ 2)}$

$d=\sqrt{16}$

$d = 4$

So, the distance is $d = 4$

Answer:

$d = 4$

Identify the biggest perfect square for 75

mr_godi [17]

Answer:

We just multiply 75 with 3 to make it a perfect square. This is because, 75 = 5 × 5 × 3. 3 doesn't have a pair. Thus 75 × 3 = 225 and √225 is 15.

D is the planar region bounded by y = 0, y = x² and x = 1. Find the value of the integral below.

MissTica

$\displaystyle \iint_D x e^y \, dA = \int_0^1 \int_0^{x^2} x e^y \, dy \,dx \\\\ ~~~~~~~~ = \int_0^1 x (e^{x^2} - 1)\, dx \\\\ ~~~~~~~~ = \frac12 \int_0^1 e^u \, du - \int_0^1 x \,dx = \boxed{\frac{e - 2}2}$
