Answer:

The answer is "Angle-Angle-Angle".

Step-by-step explanation:

Please find the image file in the attachment.

The angle of an image, composed of two rays at such a popular end-state, could be described. Angles with a tape measure are measured in degrees, When the three angles congruence between two triangles, that is NOT the congruence of a triangle.

Although the problem above may look really different or much harder than any equation we have solved before, guess what?! It’s n
defon

Answer:

4b+8 = 20

---------------

4b = 20

-------------------

b = 5

Step-by-step explanation:

We need to solve for b in the following equation:

\frac{4b + 8}{2}  = 10

When we multiply each term by 2 the denominator cancels out:

\displaystyle 2 \times \frac{4b + 8}{2}  = 10 \times 2\\\\4b + 8 = 20

Next, we subtract 8:

4b +8 - 8 = 20 - 8\\4b = 20

Final step, we isolate the variable. We cancel the multiplication on the left side when dividing by 4 on each term

\displaystyle 4b = 20\\\\\frac{4b}{4} = \frac{20}{4}\\\\b = 5

2+d=2-3(d-5)-2 Pls show work
defon
2 + d = 2 - 3(d- 5) - 2

First, cancel 2 on both sides. / Your problem should look like: d = -3(d - 5) - 2
Second, expand. / Your problem should look like: d = -3d + 15 - 2
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like: d = -3d + 13
Fourth, add 3d to both sides. / Your problem should look like: d + 3d = 13
Fifth, add d + 3d to get 4d. / Your problem should look like: 4d = 13
Sixth, divide both sides by 4. / Your problem should look like: d =  \frac{13}{4}

Answer as fraction: d =  \frac{13}{4}
Answer as decimal: d = 3.25
