1.) B. 245m^2
2.) D. 17.64cm^2
3.) B. 245m^2
4.) A. 3.91 mi^2
5.) C. 15.36cm^2

Remember! In order to find the area of a triangle, you must multiply the base by the height, then divide by 2!

I hope this helps!

Find the greatest number which divides by 1280 and 1371 leaves a remainder in each case?

vladimir1956 [14]

1279???
Because the gcf does not leave any remainders behind. The gcf could be 1280, but that would not leave a remainder behind if you divided 1280 by 1280. So, I think it is 1279, but i am probably wrong

Find the area of a triangle when a = 19.2, A = 53.8°, and C = 65.4 Round to the nearest tenth.

Tju [1.3M]

Answer:

$A=181.0\ units^2$

Step-by-step explanation:

step 1

Find the length side c

Applying the law of sines

$\frac{a}{sin(A)}=\frac{c}{sin(C)}$

substitute he given values

$\frac{19.2}{sin(53.8^o)}=\frac{c}{sin(65.4^o)}$

solve for c

$c=\frac{19.2}{sin(53.8^o)}sin(65.4^o)\\\\c=21.6\ units$

step 2

Find the measure of angle B

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

$A+B+C=180^o$

substitute the given values

$53.8^o+B+65.4^o=180^o\\B=180^o-119.2^o\\B=60.8^o$

step 3

Find the area of the triangle

we know that

The area of the triangle applying the law of sines is equal to

$A=\frac{1}{2}(a)(c)sin(B)$

substitute the given vales

$A=\frac{1}{2}(19.2)(21.6)sin(60.8^o)\\\\A=181.0\ units^2$

complete the equation 8.9 x □ = 8900 using a power of 10 explain how the product will change if the exponent changes.

Tju [1.3M]

The value that will go into the empty space will be $10^3$

<h3>Expoenential functions</h3>

The standard exponential function is given as A*10^n

A is an integer between 1 and 10
n is an integer

Given the value 8900. The standard form written as a scientific notation is expressed as $8.9 \times 10^3$

Hence the value that will go into the empty space will be $10^3$
