PLS HELP DUE SOON!!!!:(
Len [333]

Answer:

I don't know how to answer question 1, but the answer from question 2 is x=5

Step-by-step explanation:

The triangle shown is an isosceles triangle because it has two congruent sides. The base angles of isosceles triangles are congruent so ∠y=∠x. since the ∠x is 52 the ∠y is also 52. We subtract the measure of angles x and y in order to find the measure of the third angle. 180-(52+52) or 180-104 is 76. this means that 14x=6=76. All we have to do to get the answer now is solve. 76-6 is 70 and 70 divided by 14 is 5. x=5.

PLEASEEEE HELPP !
Kobotan [32]

Answer:

slope (m) = -5

Step-by-step explanation:

The slope can be calculated using two points, (2, 60) and (4, 50) as shown below:

slope (m) = \frac{y_2 - y_1}{x_2 - x_1}, where,

(2, 60) = (x_1, y_1)

(4, 50) = (x_2, y_2)

Plug in the values into the equation

slope (m) = \frac{50 - 60}{4 - 2}

slope (m) = \frac{-10}{2}

slope (m) = -5
