This is an isosceles triangle because the picture shows it has two equal sides. Isosceles triangles have two equal angles.
The sum of all the angles of a triangle = 180º.
We can use this equation to solve for x:
2x + 54 = 180.
- 54 -54 Subtract 54 from both sides.
2x = 126
/ 2 /2 Divide 2 from both sides to isolate x.
x = 63º
Let's check! 63 + 63 + 54 = 180? YUP!
Answer: M≤ $15
Step-by-step explanation:
The total number of cups in the package is 2300.
<h3>What is Percentage?</h3>
Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
Here,
Let the total number of cups in the package be x.
Number of green cup = 690
Weightage of green cup in total = 30%
Now,
30% of x = 690
30/100 X x = 690
x = 690 X 100/30
x = 23 X 100
x = 2300
Thus, the total number of cups in the package is 2300.

Answer:
A = 340 adult.
C = 398 children.
Step-by-step explanation:
Let the number of children be C
Let the number of adults be A
Translating the word problem into an algebraic equation, we have;
A + C = 738 .......equation 1
1.5C + 2C = 1306 .......equation 2
A = 738 - C .......equation 3
Substituting eqn 3 into eqn 2, we have;
1.5(738 - C) + 2C = 1306
1107 - 1.5C + 2C = 1306
1306 - 1107 = 2C - 1.5C
199 = 0.5C
C = 199/0.5
<em>C = 398 children. </em>
Now, to find the value of A.
From equation 3;
A = 738 - C
A = 738 - 398
<em>A = 340 adult. </em>
