Answer:
a = 12 ft, b = 12 ft
Step-by-step explanation:
The triangle is 45 45 90 right triangle
so a = b
Ratio of leg : hypo. = a : a√2
Given hypo = 12√2, so legs a = b = 12
Answer
a = 12 ft, b = 12 ft
Answer:11
Step-by-step explanation:
Boys : girls=7:1
Sum of ratio=7+1=8
Let number of girls be y
Then number of boys=y+66
Total number of pupils=y+y+66
Total number of pupils=2y+66
girls only=(girl ratio)/(sum of ratio) x (total number of pupils)
y=1/8 x (2y+66)
Cross multiply
y x 8=2y + 66
8y=2y + 66
Collect like terms
8y-2y=66
6y=66
Divide both sides by 6
6y/6=66/6
y=11
There are 11 girls
They are not parallel. The slopes are not the same. One is a slope of 4 the other is aslope of 5.
A triangle is a polygon with three edges and three vertices, perimeter of ΔABC = 36cm.
<h3>Congruent triangles are what?</h3>
Congruent triangles are two triangles that are identical in terms of their size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.
Triangles with equal measures are congruent.
36cm = perimeter of ΔABC
Here we have,
ΔABC ≅ Δ XYZ
So,

Therefore, perimeter of ΔABC = 36cm
