Answer:

Step-by-step explanation:

Formula -

Triangle Area - 1/2bh

Square - l x w

Triangle - 5 x 7 = 35/2 = 17.5

Since there are four triangle, we will multiply 17.5 x 4 which is equal to 70

Square - 5 x 5 = 25

Now we add both 70 and 25 which is 95

So the total surface area is 95

Answer:

Step-by-step explanation:

Area of the triangles:

A = (base × height) ÷ 2
A = (5 × 7) ÷ 2
A = (35) ÷ 2
A = 17.5
Because there are 4 triangles, we can do our answer of one triangle × 4
So, 17.5 × 4 = 70

Area of a square:

The sides of squares are the same
A = L × W
A = 5 × 5
A = 25

Put them together:

Area of triangles + area of the square = surface area
70 + 25 = suface area
70 + 25 = 95

I hope this helps!

For circle O, mCD=125° and m

Burka [1]

CA is a diameter of the circle, so $m\widehat{AC}=180^\circ$ , which means $m\angle AOB=m\angle AOD=m\widehat{AD}=180^\circ-m\widehat{CD}=55^\circ$ . Then $m\boxed{\angle ABO}=90^\circ-55^\circ=35^\circ$ .

This means $m\angle CBO=55^\circ-35^\circ=20^\circ$ . Also, if $m\angle AOB=55^\circ$ , then $m\angle BOC=180^\circ-55^\circ=125^\circ$ , which in turns tells us that $m\boxed{\angle BCO}=180^\circ-20^\circ-125^\circ=35^\circ$ .
