A "straight angle" is a straight line.
The angle of a straight line is 180 degrees.
The value of 2 angles add together to make 180
One of the angles = 89 degrees
The value of the second angle = 180-89 = 91

Step-by-step explanation:
Yes, she is correct as the given equation is:
The left hand side of the above equation can be easily solved within parentheses as it does not contain any variable but the right hand side of the equation contains the variable x.

Answer:
Step-by-step explanation:
The dog house consists of two geometric objects, triangular prism and rectangular prism.
First, find the surface area of triangular prism
The triangular prism consists of
base of triangle (b) = 3 ft
height of triangle (h) = 2.5 ft
height of prism or length of rectangle (l) = 4 ft
side of triangle or width of rectangle (w) = 2.5 ft
Now, calculate the area
area of tp = area of two triangle + area of 2 rectangle
area of tp = (2 × 1/2 × b × h) + (2 × l × w)
area of tp = (2 × 1/2 × 3 × 2) + (2 × 4 × 2.5)
area of tp = 6 + 20
area of tp = 26 ft²
Second, find the surface area of rectangular prism
The rectangular prisms consists of
length (l) = 3 ft
width (w) = 4 ft
height (h) = 2 ft
Now, calculate the area
area of rp = area of back and front rectangle + area of left and right rectangle
area of rp = (2 × l × h) + (2 × w × h)
area of rp = (2 × 3 × 2) + (2 × 4 × 2)
area of rp = 12 + 16
area of rp = 28 ft²
Third, add both of the area
area = area of tp + area of rp
area = 26 + 28
area = 54 ft²
The area of the dog house is 54 ft²
Answer:
Equation of a line is y = mx + c
where m is the gradient
c is the y intercept
<h2>a.)</h2>
y = 4x - 1
Comparing with y = mx + c
The gradient = 4
y intercept = - 1
<h2>b.)</h2>
Comparing with y = mx + c
The gradient is 1/3
The y intercept is 3
Hope this helps you
