PLS HELP 50 POINTS Calculate m∠ABC and m∠CBD, what is the value of x?

Mathematics

KATRIN_1 [288]2 years ago

Step-by-step explanation:

∠ABF = 90° (given)

∠ ABC + ∠CBD + ∠DBE = 180°

(sum of all angles in a straight line is 180°)

so now,

x + 5 + 45 + 3x + 6 = 180

4x + 56 = 180

4x = 180 - 56 = 124

x = 124/4 = 31

x = 31

therefore, in overall figure value of x is 31°.

hence,

∠ABC = x + 5° → 31 + 5 = 36°

∠CBD = 45° (given)

∠DBE = 3x + 6° → 3×31 + 6 → 99°.

Hope this answer helps you dear!

Answer:

bottom right, x = 90

bottom left, x = 40

top left, x = 28

Step-by-step explanation:

This problem uses the variable x to mean three different numbers.

This is an incorrect use of a variable.

On the bottom right, x is a right angle, so x = 90.

On the bottom left, x + 5 = 45, so x = 40.

On the top left, 3x + 6 = 90, so x = 28.

Indicate in standard form the equation of the line passing through the given point and having the given slope. r(4, 0), m = 5
Brrunno [24]
Y = mx + b....m is the slope and b is the y intercept
slope(m) = 5...(4,0)...x = 4 and y = 0
now we sub our info into y = mx + b...we r looking for b, the y intercept
0 = 5(4) + b
0 = 20 + b
-20 = b
so ur equation is y = 20x - 20...but we need it in standard form
Ax + By = C

y = 20x - 20....subtract 20x from both sides
-20x + y = -20...multiply by -1 to make x positive
20x - y = 20 <== standard form

The point P on the circle x2 + y2 = r2 that is also on the terminal side of an angle θ in standard position is given. Find the i
Brut [27]
Okay so you do not really need the circle equation. if you make a triangle with it's x length as 3 and it's y length as 4, you will be able to find the third length. Do Pythagorean theorem to find the hypotenuse. 
the hypotenuse will be five after you calculate it.

sin is opposite over hypotenuse or Y over R

so... the sin is 4/5

make sure you know what  quadrant your triangle is in for the negatives

Someone please help me thank you

Answer:

x = - 1

Step-by-step explanation:

Given

4x = x^2 - 5               Transfer 4x to the right side.

Solution

x^2 - 4x - 5 = 0          Factor

(x - 5)(x + 1)

You want the negative solution. That means that the middle sign must be plus.

x + 1 = 0                   Subtract 10 from both sides

x = - 1                       Ten on the left disappears by the subtraction process.

Is that correct?

4x = x^2 - 5

x = - 10

4*(-1) = (-1)^2 - 5

-4  = ? 1 - 5

-4 = - 4

and it does work.

Bobby catches 8 passes in 3 football games. At this rate, how many passes does he
olasank [31]

Answer:

40 passes

Step-by-step explanation:

we know that

Bobby catches 8 passes in 3 football games

so

using proportion

Find out how many passes does he  catch in 15 games

\frac{8}{3}=\frac{x}{15}\\\\x=8(15)/3\\\\x=40\ passes
