Pleeeeeeeaaaseee help. I need to find the exterior angle measurement. I will mark brainliest

Mariana [72]

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:

$a.\ \ \ A=684\ m^2$

$b.\ \ \ A=130.2 \ km^2$

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:

$Area=2(\frac{1}{2}bh), b=9, h=12\\\\=2\times \frac{1}{2}\times 9\times 12\\\\=108\ m^2$

#We then find the areas of the rectangular surfaces:

$A=lw\\\\=15\times 16+9\times 16+16\times 12\\\\=576\ m^2$

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

$A=\sum{Areas_i}\\\\=108+576\\\\=684\ m^2$

Hence, the prism's surface area is $684\ m^2$

b.Area is calculated by summing the areas of the prism's individual surfaces.

#First, calculate the areas of the right-angled surfaces:

$A=2\times \frac{1}{2}bh,\ b=12, h=4.1\\\\=2\times 0.5\times 12\times 4.1\\\\=49.2 \ km^2$

#We then find the areas of the rectangular surfaces:

$A=lw\\\\=5\times 3+3\times 10+12\times 3\\\\=81\ km^2$

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

$A=A_r+A_t\\\\=81+49.2\\\\=130.2 \ km^2$

Hence, the prism's surface area is $130.2 \ km^2$

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

Kaitlin runs 5 miles in 38 minutes. At the same rate, how many miles would she run in 57 minutes?

Goshia [24]

Answer:

7.5 miles

Step-by-step explanation:

Since she runs 5 miles in 38 minutes, she runs $\frac{5}{38}$ miles in one minute.

Hence, in 57 minutes she runs:

$ \frac{5}{38}\times 57$ miles = 7.5 miles
