Luda [366]

Answer:

74.05 degree

Step-by-step explanation:

A ladder leans against a building. The foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building.

The ladder forms a right angle triangle with the building

Base of the triangle is 2 feet

The distance between the ground and the top of the ladder is 7 feet

the graph is attached below

AB= 2, AC = 7

We know the opposite and the adjacent side so we use tan formula

$Tan (x) = \frac{opposite}{adjacent} =\frac{AC}{AB} = \frac{7}{2}$

x = tan^-1 (7/2)

x = 74.05 degree

7. Suppose you earn $15 for each car you wash. Which function describes the relationship

Arturiano [62]

Answer:

E(c) = 15c

Step-by-step explanation:

If I earn $15 for each car i wash and my total earnings are E then we have to form a function which describes this relationship.

My earning for one car wash = $15

Similarly my earnings for c car washes = $15×c

This total earning is equal to E so function representing the equation will be E(c) = 15c

Answer is E(c) = 15c which describes the relashionship of my earnings to the number of cars i wash.

What is the missing angle

noname [10]

$Answer ☘️$

★ Important points to know

${\boxed{ \bold{Exterior \: Angle \: Theorem : - }}}$

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
$\pink{ ↪ \sf \angle \: C + \angle \: D = \angle \: B}$

★ Let's solve :-

$\sf ↪\angle \: 65 \degree + \angle \: 30 \degree =\angle \:B\\ \\ \sf ↪\angle \: 95 \degree = \angle \:B$

Hence option A 95⁰ is the right ans ✓
