Answer:
(a) <AED=50°
(b) <DAB=65°
(c) <BCD=45°
(d) Reflex <ABC=225°
Step-by-step explanation:
(a) 180-65-65=50
(b) 180-115=65 (ADC is 115)
(c) 180-135-45
(d) Reflex <ABC 360-135=225
Surface area is the area of the faces added together.
First lets find the area of one of the triangles.
Area of triangle is 1/2*base*hight
Area=1/2*2*3= 3
Area of ONE tringle is 3, and area of the FOUR tringles is 4*3 whihc is 12
Now lets find area of square
area of square is side*side
So, area is 2*2 which is 4
Now lets add area of triangles+area of square
12+4 which 16
Surface area is 16
Answer:
SEVEN!!!!
Step-by-step explanation:
<em>*Because of BODMAS, 1/2x=x/2.</em>
1/2x+3/4=1
1/2x+3/4=4/4
1/2x=4/4-3/4
1/2x=1/4
x/2=1/4
x=2/4
x=1/2
Answer is UY Because they both connect her causing an intersection
