Answer:

∠BOC = 100°

Step-by-step explanation:

Given that,

∠BOC = 25x

and

∠COD = 20x

We need to find the measure of ∠BOC.

BOD is a straight line. Here, linear pair will form. So,

∠BOC+∠COD=180

25x+20x=180

45x=180

x=4

So,

∠BOC = 25(4)

= 100°

So, the measure of ∠BOC is equal to 100°.

What is the area of the figure?
Kipish [7]

Answer:

17.98 square meters

Step-by-step explanation:

find the area of rectangle

length x width

6.2x1.8= 11.16

find area of triangle

base x height x 1/2

base= 6.2

height= 4-1.8= 2.2

area=2.2 x 6.2 x 1/2 = 6.82

add both together to get area of figure

6.82 + 11.16 = 17.98

The floor of a triangular room has an area of 32 1/2 sq.m. If the triangle’s altitude is 7 172 m, write an equation to determine
sineoko [7]

Answer:

\frac{(2)A}{h} =b

b=0.00906m

Step-by-step explanation:

Hello! To solve this exercise we must remember that the area of ​​any triangle is given by the following equation

A=\frac{bh}{2}

where

A=area=32.5m^2

h=altitude=7172m

b=base

Now what we should do take the equation for the area of ​​a rectangle and leave the base alone, remember that what we do on one side of the equation we must do on the other side to preserve equality

A=\frac{bh}{2} \\\frac{2}{h} A=\frac{bh}{2} \frac{2}{h} \\

\frac{A(2)}{h} =b

solving

\frac{2(32.5)}{7172} =0.0090[tex]\frac{A(2)}{h} =b\\b=0.00906m
