square tan theta
(tan^2) + 1 = sec^2
so sec^2 = 11/4
sec = - (sqrt 11)/2
cos= - 2/ (sqrt 11)
answer choice a if you simplify
13x-8y=12
Use the slope intercept form to solve the problem.
y = mx+b when the slope is m and the y-intercept is b.
Slope: 13/8
Y-intercept: -3/2
Answer:
A. Yes. This can form an Acute Isosceles triangle with 2 equal sides and no angles over 90 degrees and the sum of two sides is larger than the third.
B. No. The sum of two sides must be larger than the third.
C. Yes. He can use A and B, A and C or B and C.
D. He can't create 2 rectangular gardens with the six pieces of wood. He needs 4 pieces for the first rectangle which leaves only 2 pieces for the second rectangle. Rectangles must have 4 sides.
He can create 2 triangular gardens. Triangles only require 3 sides which means he can make 2 triangular gardens.
E. If the chain is 12 feet long, it has the following area:
Area = = 3.14 * = 3.14 * 144 = 452.16 square feet

Answer:
21=x
Step-by-step explanation:
Those angles will add up to 180.
So make your equation 180=3x-3+5x+15
Add like terms, so 3x+5x=8x and -3+15=12
Now you have 180=8x+12
Subtract 12 from both sides, leaving you with 168=8x
Divide by 8 on both sides.
21=x
Answer:
x = 12.29
Step-by-step explanation:
present value of the claim = x² / (1 + 2%)¹⁵ = 0.743x²
present value of the 10 premiums:
x + x/1.02 + x/1.02² + x/1.02³ + x/1.02⁴ + x/1.02⁵ + x/1.02⁶ + x/1.02⁷ + x/1.02⁸ + x/1.02⁹ = x + 0.9504x + 0.9612x + 0.9423x + 0.9238x + 0.9057x + 0.888x + 0.8706x + 0.8535x + 0.8368x = 9.1323x
0.743x² = 9.1323x
x² / x = 9.1323 / 0.743
x = 12.29
