Answer:
5) 34° 6) 17° 7) ? 8) ? 9) 50° 10) ? You do 7, 8 and 10
Step-by-step explanation:
Let x = the measure of the unknown angle in each case
5) tan x = 10/15 arctan 10/15 = 34
6) tan x = 10/32 arctan 10/32 = 17
7) tan x = 3/8 You do this one
8) tan x = 4/6 You do this one
9) sin x = 26/34 arcsin 26/34 = 50
10) tan x = 20/37 You do this one
You need to learn the definitions of sin, cos, tan, i.e sin x = opp/hyp
cos x = adj/hyp and tanx = opp/adj
opp means opposite side of x
adj means the leg of the right triangle that is a side of x
hyp means the hypotenuse of the right triangle
Answer:
Area=32 square inches
Step-by-step explanation:
<em>Step 1: Determine the dimensions of the rectangle</em>
Width=w
Length=2×w=2 w
<em>Step 2: Determine the perimeter of the rectangle</em>
P=2(L+W)
where;
P=perimeter
L=length
W=width
In our case;
P=24 inches
W=w
L=2 w
replacing;
2(w+2 w)=24
2(3 w)=24
6 w=24
w=24/6=4
The width of the rectangle=4 inches
The length of the rectangle=2×4=8 inches
<em>Step 3: Determine the Area of the rectangle</em>
Area=length×width
where;
length=8 inches
width=4 inches
Area=8×4=32 square inches
