Given ∆ABC≅∆PQR, mb=8v-9 , find m 31°<br> b.<br> 52°<br> c.<br> 49°<br> d.<br> 32°
Ipatiy [6.2K]
Here, 5v+6 = 8v-9
8v - 5v = 6 + 9
3v = 15
v = 15/3
v = 5

So, m<b = 5(5) + 6 = 25 + 6 = 31
As they are congruent, m<q would be same [ 31 degree ]

In short, Your Answer would be Option A

Hope this helps!

Mira has breakfast at a restaurant. She leaves a 20\%20%20, percent tip of \$1.80$1.80dollar sign, 1, point, 80.
elena55 [62]

Answer:

$9.00

Step-by-step explanation:

Given that $1.8 is 20% of the breakfast cost.

-We can use proportions to find the 100% cost of the breakfast before the tip.

-Let x be the full breakfast cost:

0.2=1.8\\1.0=x\\\\0.2x=1.8\times 1.0\\\\\\x=\frac{1.8}{0.2}\\\\=9

Hence, the full breakfast cost is $9.00 before the tip.
