In a triangle, Angle B is twice as large as Angle A. Angle C is five more than
Angle B. Write and solve an equation to find the measure of Angle A.
Answer:
<A = 35 degrees
Step-by-step explanation:
<A = x
<B = 2x
<C = 2x + 5
X + 2x + 2x + 5 = 180 degrees
5x + 5 = 180
5x = 180 -5
x = 175/5
x = 35

The measure of an angle is 6 greater than half the measure of it’s supplement. Find the measure of the angle
Answer:
64°
Step-by-step explanation:
Set the measure of the original angle as x.
The measure of its supplement would be 180-x.
Thus,
x = 0.5 * (180-x) + 6
x = 90 - 0.5x + 6
1.5x = 96
x = 64°
The measure of angle is 64 degree.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
The measure of an angle is 6 greater than half the measure of it’s supplement.
let the angle be x
supplement of x= 180- x
and, 6 greater than half the measure of it’s supplement.
x = 6 + 1/2( 180- x)
x= 6 + 90 - x/2
x+ x/2 = 96
3x/2 = 96
x= 32 x 2
x= 64
Hence, the measure of angle is 64 degree.

Step-by-step explanation:
Assuming GH≅BC
You can write this equation to represent the problem:

Then, just solve for z:
[tex]7z=4z-3+1\\7z-4z=-2\\3z=-2\\z=-\frac{2}{3}[/tex]

What's the difference between a ball and a sphere?
A sphere is a two-dimensional surface embedded in three-dimensional space, while a ball is the interior of a sphere (which may or may not include the sphere itself).
A sphere and ball of radius r centered at the origin are respectively described by the equation and inequality,
x² + y² + z² = r²
and
x² + y² + z² < r²
or
x² + y² + z² ≤ r²

Answer:
Step-by-step explanation:
The first thing you must do is ignore the slope which is the number multiplied by x.
The y intercept occurs when x = 0. So all you look at is the sign that follows x and the number after the sign.
The answer is
y = -5x - 12
y = -0.5x - 5
y = -0.5x + 0.5
y = -4.5x + 3
y = 2.5x + 10
Notice choosing the numbers in front of x make no sense. The order seems to be random (and it is). But the number after the x is arranged from smallest to largest.
Answer: y = -5x - 12
y = -0.5x - 5
y = -0.5x + 0.5
y = -4.5x + 3
y = 2.5x + 10

Robinson's tapestries all measure 1.5m x 1m wide. Express the proportion of the tapestries' height to width using whole numbers
and ratio notation.
The proportion of the tapestries' height to width using whole numbers is 3:2
proportions are expressed as the ratio ratio two integers. For instance a/b is the ratio of a to b
Given the following sides it a tapestries
Width = 1m
Height = 1.5m
Taking the ratio of the height to the width is expressed as;
Ratio = 1.5 : 1
Writing as a fraction
Ratio = 1.5/1
Ratio = 1.5
Ratio = 15/10
Ratio = 3:2
Hence the proportion of the tapestries' height to width using whole numbers is 3:2
