Answer:

Step-by-step explanation:

Since we see the whole angle is 90° and it's split into two smaller angles, 7x° and 11x°, then we can conclude that 7x°+11x°=90°

How do I solve this problem

Rufina [12.5K]

X+5+2x-2+90=180. combine like terms and solve like a normal algebra problem to find x. if you need to find the answer for a certain angle, plug in the value you got for x into one of the angle equations

Answer:

Principle (P) = $2,512.56 (Approx)

Step-by-step explanation:

Given:

Interest annually (R) = 9.5% = 0.095

Amount need (A) = $9500

Time period (T) = 14 years

Find:

Principle (P)

Computation:

A = P[e^(R*T)]

9,500 = P[e^(0.095 x 14)]

9,500 = P[3.781]

P = 9,500 / 3.781

Principle (P) = $2,512.56 (Approx)

The coordinate of point T are (3,-11). The midpoint of line ST is (3,-9). Find the coordinates of point S

svetlana [45]

Answer:

(3,-7)

Step-by-step explanation:

Midpoint Formula

(3,-9) = ((3+x)/2 , (-11+x)/2)

Solve for x coordinate

$3 = \frac{3 + x}{2} \\ 6 = 3 + x \\ 3 = x$

Solve for y coordinate

$- 9 = \frac{ - 11 + x}{2} \\ - 18 = - 11 + x \\ - 7 = y$

Therefore point s is (3, -7)
