Mathematics
1 answer:
ZanzabumX [31]3 years ago
8 0

Answer:

20 cm

Step-by-step explanation:

Find the area of the square first ( b x h ) then the area of one of the triangles (1/2 b x h). The sqaures base is 3 and height is 4 so the area is 12 ( 3 x 4 = 12) and the triangles you multiply the base x height again, and divide it in half

( 2 x 4 1/2). This leaves you with twenty.

Pls help me with this question and pls don't answer if you don't know. thank you,
polet [3.4K]

Answer:

I apologize if this was poorly explained. The explanation for each is below the angle.

Since these triangles are in a rectangle, The top and bottom triangles are congruent, and the left and right triangles are congruent. All 4 triangles are also Isosceles. (Two equal sides/angles)

m<1= 59

(Left and right triangles are congruent)

m<2=31

(Top and bottom triangles are congruent)

m<3= 59

(Directly across from the other 59)

m<4=31

(Each of the rectangles corner angles totals to 90 degrees, therefore making this angle 31 degrees.)

m<5=31

(Since the triangles are isosceles, this angle is also 31)

m<6= 59

(Since m<5 is 31, this angle is 59.)

m<7=118

{(Two other angles in the triangle) 31+31= 62 180-62= 118)}

m<8=62

{(Two other angles in the triangle)59+59= 118. 180-118= 62}

m<9=62

(This angle and m<8 are congruent.)

m<10=118

(This angle and m<7 are congruent.)

m<11=31

(Same reason as m<4)

I hope this helps!

Marat540 [252]

Answer:

Sacramento is 8cm from San Francisco.

8cm in map = 91 miles

91/8 = 11.375

1cm in map = 11.375 miles

Sacramento is 7 cm away from Modesto.

7 · 11.375 = 79.625

The actual distance is 79.625 miles
