Answer:

1. C

2. B

3. B

Step-by-step explanation:

Vertical angles are the angles opposite each other when two lines cross, thus angles with measures (x+77)° and 126° are vertical angles.

Vertical angles are congruent.

Hence,

$x+77=126\\ \\x=126-77\\ \\x=49^{\circ}$

What is the unit rate of 1.49 for 10

kap26 [50]

If you mean it costs $1.49 to buy 10 items, then the unit rate is $0.15 or 15 cents

This is because you divide 1.49 over 10 like so: 1.49/10 = 0.149, then round this to the nearest penny to get 0.15

0.15 dollars = 15 cents

so basically whatever this item is, it costs 15 cents per item

Step-by-step explanation:

base² + Altitude² = Hypotenuse²

x² + 9² = 13²

x² + 81 = 169

x² = 169 - 81

x² = 88

x = $\sqrt{88}$

$x = \sqrt{2*2*2*11}=2\sqrt{2*11}\\\\x=2\sqrt{22}$
