The answer is 14. I divided 42 by 3 and then times that answer by 1.
The measure of the vertex angle of the isosceles Δ is 96°
Step-by-step explanation:
In the isosceles triangle
- Two sides are equal in lengths
- The angle between the two equal sides is called vertex angle
- The other two angles are called base angles
- The base angles are equal in measure
∵ The measure of one of the base angles of an isosceles Δ = 42°
- The base angles are equal in measure
∴ The measure of the other base angle = 42°
∵ The sum of the measures of the interior angles of any Δ = 180°
∴ 42 + 42 + measure of the vertex angle = 180
∴ 84 + measure of the vertex angle = 180
- Subtract 84 from both sides
∴ measure of the vertex angle = 96°
The measure of the vertex angle of the isosceles Δ is 96°

Answer:
B
Step-by-step explanation:
The pattern is square numbers so
1, 4, 9, 16, 25
Equivalent fractions can be found by multiplying numerator and denominator by the same number.
for example : 2/5 * 3/3 = 6/15......2/5 and 6/15 are equivalent. Just like 2/5 * 4/4 = 8/20......2/5 and 8/20 are equivalent...so basically, if u multiply the numerator by a certain number, and the denominator by that same number, u will get an equivalent fraction.
Now to ur problem...
x 54
------ = -----
7 42
now look at ur denominators....7 x what = 42 ? 7 x 6 = 42...so u have multiplied the denominator by 6....so u would have to multiply the numerator by 6.....or divide by 6....54/6 = 9.....or 9 x 6 = 54. So that missing value is 9.
9/7 = 54/42
check..
9/7 * 6/6 = 54/42 (equivalent)
