If tan 0=3/4 find sin0

bija089 [108]

Answer:

sin O = $\frac{3}{5}$

Step-by-step explanation:

given tan O = $\frac{3}{4}$ = $\frac{opposite}{adjacent}$

Then this is a right triangle with legs 3 and 4

Using Pythagoras' identity then the hypotenuse (h ) is

h = $\sqrt{3^2+4^2}$ = $\sqrt{25}$ = 5, hence

sin O = $\frac{opposite}{hypotenuse}$ = $\frac{3}{5}$

Use the graph or table to write a linear function that relates y to x.

Lubov Fominskaja [6]

Y= -5x
Every time you multiply x with -5 you get y Ex: -5 • 3 = -15

What is the area of a triangle with a height of 14 feet and a base of 10 feet

timama [110]

Answer:

Area is 70ft

Step-by-step explanation:

Area of a triangle is A=b × h/ 2 or A=1/2×bh

Let height equal h & base equal b

So,

h=14

b=10

Solve,

A=1/2×14×10

A=1/2×140

A=70

Therefore, the area is 70 feet

Given each of the following areas, what would be the radius of each circle? a. A = 530.66 m2 b. A = 907.46 sq. ft. c. A = 379.94

ra1l [238]

Area for a circle is $A= \pi r^2$ . We will fill in each area and then solve for the radius. $530.66m^2= \pi r^2$ and $\frac{530.66m^2}{3.14}=r^2$ . ∴ $169=r^2$ and r = 13. For b, $907.46ft^2= \pi r^2$ and $\frac{907.46ft^2}{3.14}=r^2$ . $289=r^2$ , ∴ r = 17. For c, $379.94mi^2= \pi r^2$ , and $\frac{379.94mi^2}{3.14}=r^2$ . ∴, $121=r^2$ and r = 11. For d, $1962.5cm^2= \pi r^2$ , and $\frac{1962.5cm^2}{3.14}=r^2$ . ∴, $625=r^2$ so r = 25. And there you have it!
