Answer:

x=15 degrees

Step-by-step explanation:

The given triangle is isosceles, so both base angles are both (3x+18).

We also know that angles on a line add up to 180 degrees, so

(3x+18) + (8x-3) = 180 degrees

Simplify

11x + 15 = 180 degrees

11x = 180-15 = 165

Divide by coefficient on left-hand side

x = 165/11 = 15 degrees.

In a class of all girls, 22 of the 28 students have brown hair. What is the

Verdich [7]

Answer:

$\frac{3}{14}$

Step-by-step explanation:

Total Students = 28

Brown Hair = 22

NOT Brown Hair = 28 - 22 = 6

The probability of an event is the number of that event divided by total number.

So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:

P(NOT BROWN) = 6/28

Reducing, we get:

P(NOT BROWN) = 3/14

Akimi4 [234]

Answer:

ln (m^2n^9)

Step-by-step explanation:

Rule: ln a + ln b = ln ab

Rule: ln a^n = n * ln a

2 ln m + 9 ln n =

= ln m^2 + ln n^9

= ln (m^2n^9)

= $\ln m^2n^9$
