Answer:
x=7
Step-by-step explanation:
Since this is an isosceles triangle the two angles are equal.
3x+6 = 5x-8
Subtract 3x from each side
3x+6-3x = 5x-8-3x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 = 2x/2
7 = x
Answer:
x = 7
Step-by-step explanation:
Its two angle is equal so, it is isosceles triangle.
3 x + 6 = 5 x - 8 .. ( in isosceles triangle two side are equal).
3 x + 6 = 5 x - 8
Subtract 3 x from both side
3 x - 3 x + 6 = 5 x - 3 x - 8
6 = 2 x - 8
add 8 to each side
6 + 8 = 2 x - 8 + 8
14 = 2 x
Divide each side by 2
14 / 2 = 2 x / 2
7 = x
Angle relationships with parallel lines
Answer:
85 degree
Step-by-step explanation:
The angle vertically opposite to 85 be y
y = 85 (since V.O.A are equal)
Then x and y are corresponding angles
x = 85 (since corresponding angles are equal)

Step-by-step explanation:
Given the expression
-4/5 ÷ 2
= -4/5 * 1/2
= (-4*1)/(5*2)
= -4/10
= -2/2 * 2/5
-2/5
Hence the required values is -2/5

Answer:
x = 46.7°
Step-by-step explanation:
We are given:
1.) Angle x
2.) Side opposite to angle x
3.) Hypotenuse
We have to find angle x, therefore Sin ratio would be used;
Sin(x) = Opposite / hypotenuse
Sin(x) = 4 / 5.5
x = Sin⁻¹(4/5.5)
x = 46.7°

The angle corresponding to each other of different triangle are equal.
What are similar triangle ?"Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion".
Here given,
[tex]\triangle JGR[/tex] is similar to triangle [tex]\triangle MST[/tex]
So, from the definition of similar triangle ,
angle J ≅ angle M
angle G ≅ angle S
angle R ≅ angle T
Hence, option D is correct.

how many questions out of 42 do I need to get right to score 75?
Answer:
31 questions, but it's impossible to score 75%.
Step-by-step explanation:
It's impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.
This is because 31 / 42 = 0.738... You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.
You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761... You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.

Top left Equation: [tex]\frac{2}{3} + (- 2 \frac{1}{3} ) = - 1 \frac{2}{3}[/tex]
Step-by-step explanation:
You start at 2/3, or the left side.
Since the line is directing left, you are subtracting, or adding a negative.
If you see, you are moving 7 - 1/3s to the left
7 x 1/3 = 7 / 3
7 / 3 = 2 1/3
And 2/3 + (-2 1/3) = -1 2/3

Answer:
Step-by-step explanation:
5). Triangle DEF is an equilateral triangle.
Therefore, measure of all sides and the angles of the triangle will be equal.
DE = EF = DF = 5.2 ft
3y + 1 = 5.2
3y = 5.2 - 1
3y = 4.2
y = 1.4
Similarly, m∠D = 60° [Measure of all angles of an isosceles triangle = 60°]
(5x)° = 60°
x = [tex]\frac{60}{5}[/tex]
x = 12
6). Property to be used in ΔFGH,
"Two sides of an isosceles triangle are equal in measure and opposite angles of the equal sides of the triangle are equal"
FG = GH
3y = 12.9
y = 4.3
m∠F = m∠H
4x = 44
x = 11

Solve the equation below for x.
3.25x = 8.125
Answer:
x = 2.5
Step-by-step explanation:
3.25x = 8.125
Divide each side by 3.25
3.25x/3.25 = 8.125/3.25
x =2.5
Answer:
x = 2.5
Step-by-step explanation:
3.25x = 8.125
then divide both sides by 3.25 to get x on its own
x = 2.5
