Calculate the side lengths a and b to two decimal places. Will give five stars and brainliest to the first answer!!!!! Need help

garri49 [273]

Answer:

Using the Sine Rule , which states that

$\frac{a}{Sin A}=\frac{b}{Sin B}=\frac{c}{SinC}$

In Δ ABC

∠A +∠B+∠C=180°→→Angle Sum Property of Triangle

72°+85°+∠C=180°

∠C=180° - 157°

∠C= 23°

All the angles are in degrees.

$\frac{a}{Sin 72}=\frac{b}{Sin 85}=\frac{6.2}{Sin 23}$

Using the table of Sine, Calculating Sine Values

Sin 72°= 0.9510

Sin 85°=0.996

Sin 23°=0.390

$\frac{a}{0.951}=\frac{b}{0.996}=\frac{6.2}{0.390}\\\\ a=\frac{6.2 * 0.951}{0.390}= 15.118\\\\ b=\frac{6.2 * 0.996}{0.390}=15.833$

Among the five Options,

Option E: a= 15.09 and b=15.81 is approximately true.

What's The Answer??????????????????

Yuri [45]

$f(x) = \dfrac{x}{2} - 2$

$g(x) = 2x^2 + x - 3$

$(f + g)(x) = \dfrac{x}{2} - 2+ 2x^2 + x - 3$

$(f + g)(x) = 2x^2 + \dfrac{3}{2}x - 5$

The figures below are rectangles. Which polynomial represents the area of the shaded region? HAVE ALL MY POINTS but answer truth

Aleks04 [339]

Answer:

$7x - 1$

Step-by-step explanation:

Area of the shaded region = area of the large rectangular - area of the small rectangle

Area of rectangle is given as l*w

Area of the large rectangle = $l*w = (x + 5)(x - 1)$

Expand

$= x(x - 1) +5(x - 1)$

$= x^2 - x + 5x - 5$

Area of large rectangle $= x^2 + 4x - 5$

Area of small rectangle = $l*w = (x + 1)(x - 4)$

$= x(x - 4) +1(x - 4)$

$= x^2 - 4x + x - 4$

Area of small rectangle = $= x^2 - 3x - 4$

Area of shaded region = $(x^2 + 4x - 5) - (x^2 - 3x - 4)$

$= x^2 + 4x - 5 - x^2 + 3x + 4$

Collect like terms

$= x^2 - x^2 + 4x + 3x - 5 + 4$

$= 7x - 1$
