Answer:
Therefore
Step-by-step explanation:
Given:
triangle WXY is an isosceles triangle,
WX ≅ XY
WX = 6x-77
XY = 3x+4 and
WY = 5x-31
To Find
x = ?
measurements of each side = ?
Solution:
Δ WXY is an Isosceles Triangle ..Given
WX ≅ XY ...........Given
Substituting the values we get
Now Substituting 'x' in WX, XY, and WY we get
Therefore
Answer:
Surface area = 505cm²
Step-by-step explanation:
Surface area of the triangular prism. = 2B + ph
B is the base area
p is the perimeter of the triangle
h is the height of the triangle
Base area = 1/2 * base * height
Base area = 1/2 * 18 * 40
Base area = 9 * 40
Base area = 360cm²
Perimeter of the triangle = 41 + 41 + 18
Perimeter of the triangle = 100cm
height of the prism = 45cm
Surface area = 360 + 100 + 45
Surface area = 505cm²

Answer:
a. 601
b.
Step-by-step explanation:
a. The number of students in the school who study french:
The number of boys who study french + The number of girls who study french:
= (3÷7)×644+(5÷8)×520
= 601
b. the probability that a student does NOT study French :
= P(boy does not study french) + P(girl does not study french)
