Answer:

∠CED = 15° .

Step-by-step explanation:

Given : Figure .

To find : What is the measure of ∠CED.

Solution : We have given Two triangle ABC and CDE.

We need to measure of ∠CED.

In triangle CDE , Angle ∠DCE = 90 °.

∠CDE = 75°.

By the angle sum property of the triangle : Sum of all the triangle is 180°.

∠CED + ∠CDE +∠DCE = 180 .

Plug the values

∠CED + 75 + 90 =180 .

∠CED + 165 = 180 .

on subtracting both sides by 165.

∠CED = 180 - 165 .

∠CED = 15° .

Therefore, ∠CED = 15° .

You take 90 + 75 = 165 and then 180 - 165 = 15 degrees so that’s your answer

Answer:

rhombus

A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles. Kites have two pairs of adjacent sides that are equal.

Find the domain of f/g

san4es73 [151]

Answer:

C. All real numbers except 3/4

Step-by-step explanation:

We are given

$f(x)=3x^2+x^4+2$

$g(x)=4x-3$

Firstly, we will find f/g

$\frac{f}{g}=\frac{3x^2+x^4+2}{4x-3}$

Domain:

We know that domain is all possible values of x for which any function is defined

so, we know that denominator of any function can not be zero

so, firstly we set denominator =0

and then we can solve for x

$4x-3=0$

Add both sides by 3

$4x-3+3=0+3$

$4x=3$

$x=\frac{3}{4}$

so, this function is defined for all values of x except at

$x=\frac{3}{4}$

Domain will be

All real numbers except 3/4
