Answer:
2a = 108
Step-by-step explanation:
the 3 angles of the triangle add to 180
lets call the unknown angle in the triangle y
a+10 + y + 44 = 180
we also know that 2a+ y = 180 because it makes a straight line
solve this for y by subtracting 2a from each side
2a +y = 180
y = 180 -2a
now we can substitute this into the triangle equation
a+10 + y + 44 = 180
a+10 + 180 -2a + 44 = 180
combine like terms
-a +234 = 180
subtract 234 from each side
-a = --54
divide each side by -1
a =54
the exterior angle is 2a
2* 54
108
Answer:


Step-by-step explanation:
a. Area is calculated by summing the areas of the prism's individual surfaces.
#First, calculate the areas of the right-angled surfaces:

#We then find the areas of the rectangular surfaces:

#We sum the areas to find the total surface areas:

Hence, the prism's surface area is

Answer:
160m
Step-by-step explanation:
Since the rectangles are similar and we have their proportion of coefficient, the larger rectangle is twice the smaller rectangle. Therefore we multiply the smaller rectangle by 2.
Hence;
(80 × 2)m
= 160 m
Answer:
7.5 miles
Step-by-step explanation:
Since she runs 5 miles in 38 minutes, she runs
miles in one minute.
Hence, in 57 minutes she runs:
$ \frac{5}{38}\times 57$ miles = 7.5 miles
