What is the area of this triangle?
Diano4ka-milaya [45]

ANSWER

56.1 square inches.

EXPLANATION

The area of this triangle can be calculated using the formula,

Area =  \frac{1}{2} ab \sin( C)

where a=8in.

b=14.2 in.

and C=99° is the included angle.

We plug in these values to obtain,

Area =  \frac{1}{2} \times  8 \times 14.2 \sin( 99 \degree)

Area = 56.1007

We round to the nearest tenth to get,

56.1 sq. inch

Complex numbers simplify square roots of negative numbers
Bogdan [553]

Lets do

\\ \sf\longmapsto \sqrt{-100}

\\ \sf\longmapsto \sqrt{-(10)^2}

\\ \sf\longmapsto \sqrt{10^2}\sqrt{-1}

\\ \sf\longmapsto 10i

Write in standard form

\\ \sf\longmapsto 10i

\\ \sf\longmapsto \boxed{0}+\boxed{10}i

Simplify the expression, only odds 9-17
Elodia [21]

All exercises involve the same concept, so I'll show you how to do the first, then you can apply the exact same logic to all the others.

The first thing you need to know is that, when a certain quantity multiplies a parenthesis, you can distribute that number to every element in the parenthesis. This means that

a(b+c) = ab+ac

So, a is multiplying the parenthesis involving b and c, and we distributed it: a multiplies both  b and c in the final result.

Secondly, you have to know how to recognize like terms, because they are the only terms you can sum. Two terms can be summed if they have the same literal expression. So, for example, you cannot sum 3x+2y, and neither 5x^2-4x exponents count.

But you can su, for example,

5x-3x = (5-3)x = 2x

or

23xy^2z^6 - 17xy^2z^6 = 6xy^2z^6

So, take for example exercise 9:

1.2(7x-5y) - (10y-4.3x)

We distribute the 1.2 through the first parenthesis:

1.2(7x-5y) = 1.2 \cdot 7x - 1.2 \cdot 5y = 8.4x-6y

And you can distribute the negative sign through the second parenthesis (it counts as a -1 to distribute):

- (10y-4.3x) = -10y+4.3x

So, the expression becomes

8.4x-6y-10y+4.3x

Now sum like terms:

(8.4+4.3)x + (-6-10)y = 12.7x - 16y
