Answer:

1) n^2 – 3 n + 8 4^2 – 3*4 + 8 = 12

2) (x^2 – 4 y) / 2 (16 + 12) / 2 = 14

3) 4 * |-7 – 2| = 4 * 9 = 36 Abs -9 = 9

4) 19 – x^2 = 19 – 25 = -6 (-5)^2 = 25

5) S^2 t – 10 = -8^2 * ¾ -10 = 64 * ¾ - 10 = 38

6) 4 p^2 + 7 q^3 = 4 * 9 + 7 * (-8) = - 20 (-2)^3 = -8

What is the measure of angle CXE?

miskamm [114]

Given:

m∠CXD = 30°

m∠DXE = 30°

To find:

The measure of angle CXE.

Solution:

The measure of angle CXE is sum of the measures of angle CXD and DXE.

⇒ m∠CXE = m∠CXD + m∠DXE

⇒ m∠CXE = 30° + 30°

⇒ m∠CXE = 60°

The measure of angle CXE is 60°.

PLEASE HELP ASAP!!!!!

Wittaler [7]

Answer:

$sec(x)$

Step-by-step explanation:

$cos(x)+cos(x)tan^2(x)$

Multiply cos(x) by 1:

$cos(x)*1+cos(x)tan^2(x)$

Factor out cos(x):

$cos(x)(tan^2(x)+1)$

Apply the pythagorean identity ( $tan^2(x)+1=sec^2(x)$ ):

$cos(x)sec^2(x)$

Rewrite $sec^2(x)$ :

$cos(x)(\frac{1}{cos(x)})^2 \\cos(x)\frac{1}{cos^2(x)}$

Cancel cos(x):

$\frac{1}{cos(x)}$

Rewrite:

$sec(x)$

PLEASEE help me ! :(

Mashutka [201]

HELLO EVERYONE,

TO FIND Y:

We know

a straight line makes an angle of 180

so,

180 = 119-y

180-119 = y

therefore y is

y = 59 degrees

TO FIND X:

We know,

all angles of a quadrilateral make a sum of 360,

so,

A+B+C+D = 360

HERE,

A = 131

B = 56

C = Y = 59

D = X

131 +56+59+X = 360

360 - 246 = X

X = 114 Degrees

Please do mark me the branliest if it helpful for you. Thanks.
