Great white sharks have triangular teeth with a height that is 1 centimeter longer than the base. if the area of one tooth is 15

lisov135 [29]

A = (H * B) / 2.......2A = H * B
A = 15
H = B + 1

2(15) = H * B
30 = B(B + 1)
30 = B^2 + B
B^2 + B - 30 = 0
(B + 6)(B - 5) = 0

B + 6 = 0
B = -6.....not this one, it cant be negative

B - 5 = 0
B = 5 <==== base is 5 cm

H = B + 1
H = 5 + 1
H = 6 <=== height is 6 cm

Change the subject of the equation v = u + at to a.

emmasim [6.3K]

<h3>Answer ↓</h3>

<h3>Calculations ↓</h3>

In order to make a the subject of this equation , we need to get a by itself .

The current equation is :

v = u + at

Subtract u on both sides :

v-u=at

Now, divide by t on both sides :

v-u/t=a

<h3>So the formula looks like ↓</h3>

$\boxed{\\\begin{minipage}{3cm}Equation \\ a=$\displaystyle\frac{v-u}{t} $ \\ \end{minipage}}$

Find the angle measure that makes the statement true. Sin 25° = Cos ____ °

givi [52]

Since the sine and cosine functions are cofunctions, they are complementary. The format for this is that sinx=cos(90-x). This works for secant and cosecant and tangent and cotangent. So, sin25°=cos65°.

<u>Question</u> : 21

The lines ON and PQ are parallel, therefore

Angle O + Angle P = 180°

Angle O + 125° = 180°

Angle O = 180° - 125°

Angle O = 55°
