Answer:

4x + 8x = 180

12x = 180

divide by 12 on both sides:

X = 15

4 x 15 = 60 degrees

8 x 15 = 120 degrees

Answer:

Hello! answer: x = 15

Step-by-step explanation:

Since this is a supplementary angle it will equal a total of 180 15 × 4 = 60 15 × 8 = 120 you add these up and... 60 + 120 = 180 therefore x = 15 and

4x = 60 and 8x = 120 HOPE THAT HELPS!

In rectangle abcd, points p and q lie on side AB and DC respectively. Angle PMQ is a right angle, M is the midpoint of side BC a
nirvana33 [79]

Answer:

PM:MQ = 8:3.

Step-by-step explanation:

\rm \angle B\hat{M}P + 90^{\circ} + \angle C\hat{M}Q = 180^{\circ};

\implies \rm \angle B\hat{M}P + \angle C\hat{M}Q = 90^{\circ};

\implies \rm 90^{\circ} - \angle B\hat{M}P = \angle C\hat{M}Q.

Also,

\rm \angle B\hat{P}M = 90^{\circ} - \angle B\hat{M}P in right triangle PBM.

Thus \rm \angle{P\hat{B}M} = \angle C\hat{M}Q.

Additionally \rm \angle \hat{B} = 90^{\circ} = \angle \hat{C}.

Therefore \rm \triangle PBM \sim \triangle MCQ.

\rm \displaystyle BC = 2\;MC for M is the midpoint of segment BC.

\rm \displaystyle PB = \frac{4}{3}BC = \frac{8}{3}MC.

\rm \triangle PBM \sim \triangle MCQ implies that

\displaystyle \rm PM:MQ = PB:MC = 1:\frac{8}{3} = 8:3.

10 (> or = to)  2.00 + 0.75x

Sorry. I don't have that symbol on my keyboard. but her ten dollars has to be greater than or equal to whatever the cost is so that's why that symbol has to be used in this case. 2.00 is the flat rate and add 0.75 multiplied by however many miles she is taking!

Hope this helps!
