Answer:
144°
96+48(further away angles)
Answer:
x = 144°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle , then
x = 48° + 96° = 144°
Answer:
60 degrees
Step-by-step explanation:
Every Triangle has an angle of 180degrees
so if we add all of the written angles which is 25 + 35 + 60 = 120
we take 180 degrees and subtract it with the previous answer (120)
180 - 120 = 60
Thereforeitis60degrees
Answer:
answer is 60
Step-by-step explanation:
because if the angle is 60 degrees anywhere in the triangle means its an equilateral triangle making all the angles 60 degrees
The number of students who attended the museum opening is 80.
A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, A group of 100 people, some students and some faculty, attended a museum opening.
Assuming no. of students to be x and no. of faculty to be y.
∴ x + y = 100...(i)
Each student paid $10 per person for entrance to the museum and each of the faculty paid $25 per person for entrance and the total cost is $1300.
∴ 10x + 25y = 1300...(ii)
Now multiplying eqn(i) by 10 we get 10x + 10y = 1000...(iii)
Subtracting eqn(iii) from eqn(ii) we get 15y = 300 ⇒ y = 20 and substitting value of y in eqn(iii) we get x = 80.

STUDENTS X 10
FACULTY 100-X 25
10X + 25(100-X) = 1300
10X + 2500 -25X = 1300
10X - 25X = -2500 + 1300
-15X = -1200
15X = 1200
X = 1200/15
X = 80 STUDENTS <--------SOLUTION
