The Question is Incomplete The complete question with figure is below.

Answer:

Therefore the equation to solve for b is

\tan 30 = \dfrac{5}{b}

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠C = 90°

BC = 5 cm

AB = 10 cm

∠A = 30°

To Find:

b = ?

Solution:

In Right Angle Triangle ABC Tangent identity we have

\tan A = \dfrac{\textrm{side opposite to angle A}}{\textrm{side adjacent to angle A}}

Substituting the values we get

\tan 30 = \dfrac{BC}{AC}\\\\\tan 30 = \dfrac{5}{b}

Therefore the equation to solve for b is

\tan 30 = \dfrac{5}{b}

What does this equal y >4x - 5
Tresset [83]

Answer:

This represents the graph area above the line y = 4x - 5 shaded.

Step-by-step explanation:

y > 4x - 5 is an inequality.  First we graph y = 4x - 5, which has y-intercept (0, -5) and slope 4.  Next, we shade all of the area above this line (because the inequality y > 4x - 5 says that all y values are above 4x - 5).

Step-by-step explanation:

first find the area od the rectangle than the triangle.

to find the area count the number of squares and use A=b*h

than do the same for the triangle using A=.5*b*h

15=3*5

10.5=.5*3*7

10.5+15=25.5

This is about angles. Please answer someone?
NISA [10]
Actually, this is not about angles.  It's about the length of the sides in a right triangle.

In EVERY right triangle, the squares of the lengths of the short sides add up
to the square of the length of the longest side.  You're in high school math,so
I'm SURE you've heard that in class before ... possibly even just before you
were assigned this problem.

Let's say that again:  The squares of the lengths of the sides that meet at
the  right angle add up to the square of the length of the longest side.  In
the triangle in this particular problem, that means
                                                                             a² + b² = c²

You know the lengths of 'b' and 'c', so you shouldn't have any trouble finding
the length of 'a'.
