In triangle ABC mzA -45, mzB = 40", and a = 7. Which equation should you<br> solve to find b?

yaroslaw [1]

Answer:

Option A. $\frac{sin(45\°)}{7}=\frac{sin(40\°)}{b}$

Step-by-step explanation:

we know that

Applying the law of sines in the triangle ABC

$\frac{sin(A)}{a}=\frac{sin(B)}{b}$

substitute the given values

$\frac{sin(45\°)}{7}=\frac{sin(40\°)}{b}$

$b=\frac{7}{sin(45\°)}sin(40\°)\\\\b=6.4\ units$

Find the missing length of the triangle (I need a step by step answer please)

zhannawk [14.2K]

Answer:

c = 12.5

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem (a^2 + b^2 = c^2)

lets say 10 = a and 7.5 = b (this is because they are the legs of the triangle and variables a and b represent the legs of the triangle)

plug into the Pythagorean theorem.

10^2 + 7.5^2 = c^2

simplify (here you just square 10 and 7.5)

100 + 56.25 = c^2

simplify

156.25 = c^2

simplify

(here you get the square root of 156.25 and c^2, the positive square root of 156.25 is 12.5 and the square root of c^2 is c)

12.5 = c

6. Using Table 11-2 from your text, calculate the present value (principal) and the compound interest given: Compound Amount = $

storchak [24]

Answer:

The Principal is $877.19 And Compound Interest is $372.81

Step-by-step explanation:

Given as :

Amount after investment = $1250

The time period of investment = 6 years

The nominal rate = 6% compounded semiannually

Let the principal = P

From compounded method

Amount = Principal × $(1 + \frac{Rate}{2\times 100})^{2\times Time}$

Or, $1250 = P × $(1 + \frac{6}{2\times 100})^{2\times 6}$

Or, $1250 = P × $(1.03)^{12}$

Or, $1250 = P × 1.425

∴ P = $\frac{1250}{1.425}$

I.e P = $877.19

So , Principal = $877.19

Now, Compound Interest = Amount - Principal

= $1250 - $877.19

Or, CI = $372.81

Hence The Principal is $877.19 And Compound Interest is $372.81 Answer
