Answer:
19
Step-by-step explanation:
8 x 4 = 32
32 + 6 = 38
38 / 2 = 19
The answer is 40°
i will tell you how,
Total angle sum of any triangle is 180°
∠A + ∠B + ∠E = 180°
70° + 80° + ∠E = 180°
solve for ∠E
∠E = 30°
Now solve use ∠BDE,
∠B + ∠D + ∠E = 180°
20° + 90° + 30° + x = 180° (in triangle DEB, ∠E = 30 + x ) (∠D is 90°)
solve for x
there fore, x = 40°
Answer:
37.5
Step-by-step explanation:
First you have to realize that these are similar triangles.
You can do a easy cross multiplication with these types of questions by forming an equation with the similar angles.
put the smaller above the decimal and the bigger one below like this.
=
Now cross multiply
8x=300
x=37.5
First you have to use the formula which is r to the second times height times pi
You would do 4 times 2 equals 8 then multiply 8 times 10 equals 80 then multiply that answer times 3.14 then your answer is 251.2
green pepper, onion, tomato
= 2x, 5x, 9x
Number of cups = 96
therefore 2x + 5x + 9x = 96
16x=96
x= 96÷16 = 6
Onion = 5x
therefore answer = 6 x 5 = 30
C. 30 is the correct answer :)
