Answer:

OB=4

Step-by-step explanation:

Step 1: Subtract 5 from both sides.

4x+5−5=21−5

4x=16

Step 2: Divide both sides by 4.

4x/4=16/4

x=4

Answer:

x=4

Answer:

OB: 4

Step-by-step explanation:

4x+5=21

Next step is to subtract 5 on both sides to keep it an equation.

4x=21-5

4x=16

Finally, divide by 4 on both sides for x to be alone and for it to stay and equation.

x=4!

There you go! Hope this helped, this is my first time answering a question! :p

PLS HELP ME WITH THIS QUESTION IVE BEEN DYING TRYING TO FIGURE THIS OUT
LekaFEV [45]

Answer:

y = -x - 1

Step-by-step explanation:

hello,

this is a line, right?

So the equation should be something like

y = ax+b and we need to find a and b

we can see that the points (-1,0) and (0,-1) are in the line so we can write

0 = a*(-1) + b <=> b - a = 0 <=> a = b

-1 = a*0 + b <=> b = -1

so the equation is

y = -x - 1

hope this helps

Answer:

Hence,

The measure of ∠A is 60.065°

\m\angle A= 60.065

Step-by-step explanation:

Given:

ΔABC is a Right Angle Triangle at ∠ B = 90°

BC = Opposite side to ∠A = 13 unit

AC = Hypotenuse  = 15 unit  

To Find:

m∠A = ?  

Solution:

In Right Angle Triangle ABC ,Sine Identity,

\sin A= \dfrac{\textrm{side opposite to angle A}}{Hypotenuse}\\

Substituting the values we get

\sin A= \dfrac{BC}{AC}=\dfrac{13}{15}=0.8666\\\angle A=\sin^{-1}(0.8666)\\m\angle A= 60.065\°

Hence,

The measure of ∠A is 60.065°

\m\angle A= 60.065
