Answer:
1 =98
2 = 49
3 = 63
Step-by-step explanation:
Assuming 1 is at the center since it has the dot
<1 = arc 98
<1 = 98
We can find angle 2
<2 = 1/2 the intercepted arc
<2 = 1/2 (98)
<2 = 49
We can find angle 3
Angle formed by 2 chords
<3 = 1/2(arc 70 + arc56)
<3 = 1/2(70+56)
<3 =1/2 (126)
<3 = 63
from left to right
1st triangle is = 24
small rectangle is = 24
larger rectangle is = 96
final triangle is = 12
addition of above values give the area of whole figure which is = 156 units
You have too divide 2 and 7 and 8 divided by the sum and that’s your answer
Answer:
2. x = 47
3. x = 2
Step-by-step explanation:
These problems involve proportions, or equivalent ratios. You can solve for 'x' in each by using cross-multiplication and division.
2. 28(7) = 4(x + 2)
Distribute = 196 = 4x + 8
Subtract 8 from both sides: 196 - 8 = 4x + 8 - 8 or 188 = 4x
Solve for x: x = 47
3. 2(2x + 7) = 11(3x - 4)
Distribute: 4x + 14 = 33x - 44
Add 44 to both sides: 4x + 14 + 44 = 33x - 44 + 44 or 4x + 58 = 33x
Subtract 4x from both sides: 4x + 58 - 4x = 33x - 4x or 58 = 29x
Solve for x: x = 2
The answer is (3x + 5) ^2
