Find the measure of angle A

blagie [28]

Answer:

43°

Step-by-step explanation:

(x + 53)° + (x + 74)° + 73° = 180°

(x + 53 + x + 74)° = 180° - 73°

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127

2x = - 20

x = - 20/2

x = - 10

$m\angle A = (x +53)\degree \\\\m\angle A = (-10 +53)\degree \\\\m\angle A = 43\degree \\\\$

erik [133]

Answer:

.00059 or .0006

Step-by-step explanation:

You are trying to find what won't be in the water because there are many combinations so you use a complement formula.

1-0.79=0.29

Use the left over percentage in an equation to determine the probability.

$1-(0.29)^6=0.000594823$

The exponent 6 comes from the number of locations.

Answer:

-1/60

Step-by-step explanation:

$\frac{11}{15} + (- \frac{3}{4} )\\$

= $\frac{11}{15} - \frac{3}{4}\\$

= $\frac{44}{60} - \frac{45}{60}\\$ (find LCM of demoninators)

= $\frac{44-45}{60}\\$

= $\frac{-1}{60}\\$

= -1/60

in jacks class, 18 of the students are y'all and 10 are short. in Michael class 54 students are tall and 30 students are short w

Naddik [55]

Answer:

The answer is: both class have the same ratio.

Step-by-step explanation:

Get the ratio of tall to short. Divide Tall by Short:

Jack's class:

18/10 = 1.8 tall one for every short one

Michael's class:

54/30 = 1.8

The ratio is the same!

You can further prove this by multiplying 18 times 3 and getting 54, and 10 times 3 and getting 30.

Hope this Helps!! Have an Awesome Day!! (-:
