Answer:

The slope of a trend is equal to $m=\frac{22}{9}$

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(1,3)\ B(10,25)$

Substitute the values

$m=\frac{25-3}{10-1}$

$m=\frac{22}{9}$

Work out the area of triangle give your answer to 1 decimal place

forsale [732]

<u>Given</u>:

Given that the triangle.

Let the length of the side a be 10 cm.

Let the length of the side b be 13 cm.

Let the measure of ∠C is 105°

We need to determine the area of the triangle.

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

$A=\frac{1}{2} a b \ sin \ c$

Substituting a = 10, b = 13 and ∠C = 105°, we get;

$A=\frac{1}{2}(10)(13) \ sin \ 105$

Simplifying, we get;

$A=\frac{1}{2}(10)(13)(0.966)$

$A=\frac{1}{2}(125.58)$

$A=62.79 \ cm^2$

Rounding off to 1 decimal place, we have;

$A=62.8 \ cm^2$

Thus, the area of the triangle is 62.8 cm²
