Mathematics
1 answer:
Kamila [148]3 years ago
3 0

Answer:

10

Step-by-step explanation:

Given expression:

                   20 - \frac{15 + 3(5)^{2} }{5^{2} - 4^{2}  }

     To solve this problem, we use the order of operation:

P - Parentheses

E - exponents

M - multiplication

D - division

A - Addition

S - Subtraction

  Now solve the parentheses first;

     =   20 - \frac{15 + 3x 25}{5^{2} - 4^{2}  }

     =    20 - \frac{15 + 75}{5^{2} - 4^{2} }

     Now solve the exponents:

    = 20 - \frac{15 + 75}{25 - 16}

    Now solve the division:

     = 20 - \frac{90}{9}

     = 20 - 10

     = 10

find the measure of the arc or angle indicated. assume that lines which appear tangent are tangent
Serjik [45]

Answer:

Option (1)

Step-by-step explanation:

By the property of alternate segment theorem,

"Angle formed between the tangent and the chord in a circle measures the half of the measure of the intercepted arc"

m(∠EFG) = \frac{1}{2} × m(minor arc FG)

minor arc FG = 2m(∠EFG)

                      = 2(76°)

                      = 152°

Therefore, Option (1) will be the correct option.
