What’s number 11 (same directions as below)

These two triangles are similar because they have 3 angles in common.

Step-by-step explanation:

We can tell this since they both have right angles in them. We also know that angle X and U are the same since they have the notation. And since all triangles add up to 180, and if the other two angles are the same, then the final angle must be the same too.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
