Use the diagram to answer the question.​

Step-by-step explanation:

25+105+x=180 degree(being sum of the interior angles of a triangle)

130+x=180

x=180-130

x=50 degree

B. 50

Step-by-step explanation:

total angle of triangle = 180⁰

hence,

25 + 105 + x = 180

x = 50

therefore ans is B. 50⁰

step-by-step explanation:

f

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
