Answer:

\frac{100}{a}

Step-by-step explanation:

Hello!

a% is the same as \frac a{100}.

a% of a can be found by multiplying them both, giving us \frac {a^2}{100}

<h3>Solve:</h3>
  • \frac{a}{\frac{a^2}{100}}
  • a * \frac{100}{a^2}
  • \frac{100a}{a^2}
  • \frac{100}{a}

The value of the expression is \frac{100}{a}

Bas_tet [7]

Answer:  

135

Step-by-step explanation:

if mK is 90 then mD is 60 and mS is 30. since the new point is in the middle of the triangle divide 60 and 30 by 2. Now mD is 30 and Ms is 15 so 30+15=45 so 180-45=135

PLEASE HELPPPPP. URGEENNTT!!! I DONT KNOW HOW TO SOLVE THIS
Oksi-84 [34.3K]

Answer:

A = 58.7 degrees

B = 66.9 degrees

C = 34.1 degrees

Step-by-step explanation:

<u><em>For <A:</em></u>

Tan A = \frac{opposite}{adjacent}

Tan A = \frac{23}{14}

Tan A = 1.6

A = Tan^{-1} 1.6

A = 58.7 degrees

<u>For <B:</u>

Sin B = \frac{opposite}{hypotenuse}

Sin B = \frac{23}{25}

Sin B = 0.92

B = Sin^{-1} 0.92

B = 66.9 degrees

<em><u>For <C:</u></em>

Sin C = \frac{opposite}{hypotenuse}

Sin C = \frac{14}{25}

Sin C = 0.56

C = Sin^{-1}0.56

C = 34.1 degrees
