By the law of sines, m∠EFG is such that
sin(m∠EFG) / (8 in.) = sin(m∠G) / (7.5 in)
so you need to find m∠G.
The interior angles to any triangle sum to 180°, so
m∠DEG = m∠D + m∠G + 43°
m∠DEG + m∠D + m∠G = 2 (m∠D + m∠G) + 43°
180° = 2 (m∠D + m∠G) + 43°
137° = 2 (m∠D + m∠G)
68.5° = m∠D + m∠G
But ∆DEG is isosceles, so m∠D = m∠G, which means
68.5° = 2 m∠G
34.25° = m∠G
Then
sin(m∠EFG) = (8 in.) sin(34.25°) / (7.5 in)
m∠EFG ≈ sin⁻¹(0.600325) ≈ 36.8932°

GE = 3x - 11 FD = 2.x Find GE
Can someone help me??
Answers
Answer:
22
Step-by-step explanation:
Given the following
GE = 3x - 11 FD = 2x
Let us assume GE is parallel to FD, hence GE = FD
3x - 11 = 2x
3x - 2x = 0+11
x = 11
Get GE
GE = 3x - 11
GE = 3(11)-11
GE= 33 - 11
GE = 22
Hence the length of GE is 22

What is the relationship between the side lengths of the white square and the side lengths of the triangles?
es -)
A)
Each side of the white square is congruent to shorter leg of a triangle.
B)
Each side of the white square is congruent to the longer leg of a triangle.
Each side of the white square is the hypotenuse of a triangle.
D)
Each side of the white square is congruent to both legs of the triangles.
Answers
Answer:
C) Each side of the white square is the hypotenuse of a triangle.
Step-by-step explanation:
It can be observed in the diagram that the sides of the white square forms part of the sides of the triangles. Since the triangles formed are right angled, then the longest side of the triangle is the sides of the white square.
Therefore it can be inferred that, each side of the white square is the hypotenuse of a triangle. thus the correct choice of answer is C.

Answers
Answer:
a + b = 780
Step-by-step explanation:
If we subtract the two equations we can ”eliminate“ a and b and find the value of z.
a-a = 0
b-b = 0
-10z = -700
z = 70
now we have to subistitute this value in the two equations
a + b -4(70) = 500
a + b + 6(70) = 1200
a+b - 280 = 500
a + b + 420 = 1200
If we simplify we have
a + b = 780
a + b = 780
What is the slope of a line perpendicular to the line whose equation is x+ 3y = -15 Fully simplify your answer.
Answers
Answer:
3
Step-by-step explanation:
We can find the slope of the given line in this two way:
1) the faster is calculate -a/b where a is the number the multiply x and b is the number the multiply y. In this case we have -1/3
2) the second method is rewrite the equation in slope intercept form and find the therm that multiply x
3y = -x-15
y = -1/3x - 5
Also in this case we have -1/3
Two perpendicular lines have the the product of the their slope that is -1
So the slope that we are finding is 3
In fact = 3 x -1/3 = -1

The median is 2
Step-by-step explanation:
Here, we want to get the median for the number of pencils
Firstly, we have to write out the numbers that form the box plot ; we have this as;
1,1,1,2,2,2,2,3,3,5
the median is sum of the 5th and 6th term divided by 2
The 5th term is 2
The 6th term is 2
So the median is;
(2 + 2)/2
= 4/2 = 2

10b: △BCD is A scalene triangle with all acute angles.
10c: △BDE is An Isosceles triangle with one obtuse angle.
Step-by-step explanation:
10) Looking at the diagram at the bottom left;
- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.
Thus, we can classify it as; Equilateral triangle with all acute angles.
- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.
We can classify it as;
A scalene triangle with all acute angles
- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.
Thus, we can classify it as;
- An Isosceles triangle with one obtuse angle.
