What is the equation 1.45x=0

1 answer:

3 0

1.45X=0
1.45 1.45

U divide 1.45 in each side 1.45 divided by 1.45 =x
And 1.45 divided by 0 is of course 0 cuz anything divided or
Multiplied by 0 Is always 0
Ur answer is X=1.35

Find x and each of the interior angles.

Kay [80]

Answer:

Part 1) $x=27$

Part 2) The measure of the interior angles are 64°-67°-49°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

In this problem

$(3x-17)^o+(x+40)^o+(2x-5)^o=180^o$

Solve for x

Combine like terms

$(6x+18)^o=180^o$

Subtract 18 both sides

$6x=180-18$

$6x=162$

Divide by 6 both sides

$x=27$

step 2

Find the measure of each interior angle

substitute the value of x in each measure

$(3(27)-17)=64^o$

$(27+40)=67^o$

$(2(27)-5)=49^o$

What is the value of x? sin(x+21)°=cos(2x+21)°

qaws [65]

We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90°

in this problem
(x+21)+(2x+21)=90-------> 3x+42=90-------> 3x=48-----> x=16°
