Answer:
Step-by-step explanation:
Since all the angles of triangle add up to 180 degrees,
Missing angle +100 +43=180.
Let the missing angle be 'x'.
Then, x + 100 +43 =180
or, x + 143 = 180
or, x = 180 - 143 = 37 degrees
So, the next angle is 37 degrees
Answer:
Step-by-step explanation:
The first step is to distribute.
2(2x) 2(5)
this will give you 4x and 10.
4x +10 +6=20
then, you add 10 and 6, which will give you 16
4x +16=20
next, you subtract 16 on both sides, which will leave you with 4x =4
x=1
Answer:
Option D. 8 units
Step-by-step explanation:
The given question is incomplete: here is the complete question.
Triangle FGH is an isosceles right triangle with a hypotenuse that measures 16 units. An altitude, GJ, is drawn from the right angle to the hypotenuse.
What is the length of GJ?
A. 2 units
B. 4 units
C. 6 units
D. 8 units
ΔFGH in the figure attached, is a right isosceles triangle.
m∠G = 90° and hypotenuse FH = 16 units
GI is an altitude drawn from point G to the hypotenuse.
Since this triangle is an isosceles right triangle, measure of ∠F and ∠H will be equal.
m∠F + m∠G + m∠H = 180°
m∠F + 90° + m∠F = 180°
2m∠F = 180°- 90°
2m∠F = 90°
m∠F = 45°
GJ is an altitude which will divide the hypotenuse in two equal parts. (By the property of a right isosceles triangle)
FJ ≅ GJ ≅ 8 units
Now in right triangle GJH,
tan H = 
tan 45° = 
1 = 
GJ = 8 units
Therefore, length of altitude GJ will be 8 units.
Answer:
31.5 m
Step-by-step explanation:
Let w represent the width of the pool.
Since the length is 15 m greater than the width, it can be represented by w + 15.
Use the perimeter formula, p = 2l + 2w. Plug in the perimeter, and w + 15 as l into the formula:
p = 2l + 2w
96 = 2(w + 15) + 2w
96 = 2w + 30 + 2w
96 = 4w + 30
66 = 4w
16.5 = w
So, the width of the pool is 16.5 m. Add 15 to this to find the length:
16.5 + 15
= 31.5
The length of the pool is 31.5 m
