Answer:

216 ft^2

Step-by-step explanation:

area of a triangle: (height * base)/2

in this problem,

height = 12, base = 36

area = 12*36/2 = 6*36 = 216

[Help Please!] Find the value of x.

Answers

Answer:

x = 52

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles of a triangle

x+72 = 34+90

x +72 =124

Subtract 72 from each side

x = 124-72

x =52

Answer:

x = 52 degrees

Step-by-step explanation:

Let's first focus on the angle x + 72.  Immediately adjacent to x + 72 is angle RQS.  These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees.  Then angle RQS can be expressed as

180 degrees - (x + 72 degrees), or 108 - x degrees.

The three interior angles of the triangle must add up to 180 degrees.  Hence

108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:

108 - x + 34 = 90

This yields x = 52 degrees.

(please explain how you got the slope and y-intercept with the numbers from the question if you would like brainliest)

Answers

Answer: We are using a line regression tool to solve the parameters asked in the problem. We can use online tools or that of Excel. According to the tool, the best fit values are

Slope0.3848 ± 0.03956

Y-intercept0.6053 ± 0.6370

X-intercept-1.573

1/Slope2.598

Step-by-step explanation: Best fit lines make sure that the standard deviation at each point is minimum from the best fit line.

The following triangle is an isosceles triangle. What is the length of the missing side?
A. 4 in
B. 37°
C. 53°
D. 11 in

Answers

Answer:

D.11 in

Step-by-step explanation:

isosceles triangles have two congruent sides

The missing side length is congruent with the longer side ( this is pretty obvious )

If the longer side has a length of 11in and the missing side is congruent to the longer side then the missing side length equals 11 in

Answers

area of rectangle is width × length
which means area of rectangular floor in Tamara's room = width of room × length of room
-> 95 ⅚ sq feet = 8 ⅓ feet × length of
->(95 + 5/6) sq feet = (8 + 1/3) feet × length of room
->575/6 sq feet = 25/3 feet × length of room
length of room = (575/6)/(25/3)
= 575 × 3/6 × 25)
= 23/2
