Answer:
15$
Step-by-step explanation:
Step 1: First determine the value of the whole amount, which is 50.
Step 2: Determine the percentage, which is 30.
Step 3: Convert the percentage 30% to its decimal form by dividing 30 into 100 to get the decimal number 0.3:
30/100 = 0.3
(Dividing into 100 is the same as moving the decimal point two places to the left.)
30.0 → 3.00 → 0.30
Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount:
0.3 x 50 = 15 (answer).
Hope this helps.
Answer:
54 degrees
Step-by-step explanation:
120+6= 126
180-126=54
D. 80
when you write the proportion (attached) you don't even need to solve because you see that 50/25 = 2, so 40 * 2 must be the answer. (80)
The missing angles in the triangle is as follows:
- ∠1 = 62.5°
- ∠2 = 62.5°
- ∠3 = 55°
- ∠4 = 75°
- ∠5 = 50°
<h3>How to find the measure of angles in a triangle?</h3>
A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
∠3 = 55 degrees (vertically opposite angles)
Vertically opposite angles are congruent to each other.
The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
Using exterior angle theorem ,
105 = ∠5 + 55
∠5 = 105 - 55
∠5 = 50 degrees
∠4 = 180 - 50 - 55
∠4 = 75 degrees
Therefore, the other triangle is an isosceles triangle. This means the base angles are equal.
Hence,
∠1 = ∠2 = x
2x + 55 = 180
2x = 180 - 55
2x = 125
x = 125 / 2
x = 62.5 degrees.
Hence,
∠1 = ∠2 = 62.5 degrees.
