The area of a triangle is given by the formula $A= \frac{1}{2}Bh$ , where B is the base and h is the height. We can rearrange this formula to solve for B.

$\dfrac{A}{ \frac{1}{2}h} = B\\ \\\\\dfrac{2A}{h} = B$ .

We plug in the given area, 640 square millimeters, and the given height, 32 millimeters.

$B= \dfrac{2(640)\ mm^2}{32 \ mm} = 40 \ mm$ .

40 mm is our final answer.

<h3>Answer: $580.38 (Choice B)</h3>

===================================

Work Shown:

A = P*(1+r/n)^(n*t)

A = 500*(1+0.05/4)^(4*3)

A = 580.3772588615

A = 580.38

Answer:

v = 21

Step-by-step explanation:

the sum of the interior angles of a triangle is 180 degrees

add all 3 angle measures and set equal to 180:

4v + 2v + 54 = 180

6v = 126

v = 21

Find the values of which satisfy the equation. 2 cos (2B+30°) = -√3 in the domain OP ≤B≤360°

PSYCHO15rus [73]

Answer:

60 and 90

Step-by-step explanation:

$2 \cos(2 \beta + 30) = - \sqrt{3}$

$\cos(2 \beta + 30) = - \frac{ \sqrt{3} }{2}$

$2 \beta + 30 = \cos {}^{ - 1} ( \frac{ - \sqrt{3} }{2} )$

First solution.

$2 \beta + 30 = 150$

$2 \beta = 120$

$\beta = 60$

Second solution

$2 \beta + 30 = 210$

$2 \beta = 180$

$\beta = 90$

Please help me with this geometry question, Im pretty sure you need to use SAS congruence rule

Ierofanga [76]

Congruent triangles are two or more triangles with the same length of sides and measure of internal angles. Thus the required proof is as shown below:

From the given diagram, it can be observed that:

AB = AC (similar property of two lines)

AC = AE (similar property of two lines)

Also,

m<A is a common angle to ΔABC and ΔADE

So that it can be concluded that;

ΔABC ≅ ΔADE (Side-Angle-Side property)

Thus since ΔABC ≅ ΔADE are congruent, then;

BC = DE (corresponding sides of congruent triangles)
