1) Find x
The equation is:
4x=64

x=64/4=16

answer: x=16º

2)Find y:
The equation is:
(2y)+(3y+5)=180
5y=180-5
5y=175
y=175/5
y=35

Answer: y =35º

Find the measure of each angle...
3)∠a
2y+4x+a=180
2(35º)+4(16º)+a=180º
70º+64º+a=180º
a=180º-70º-64º=46º

Answer: ∠a=46º.

4)∠b
a+b=180º
46º+b=180º
b=180º-46º
b=134º

Answer: ∠b=134º

5)∠c
a+c=180º
46º+c=180º
c=180º-46º
c=134º

Answer: ∠c=134º

6)∠d
112º+d=180º
d=180º-112º
d=68º

Answer: ∠d=68º

7) ∠e
64º+d+e=180º
64º+68º+e=180º
e=180º-64º-68º
e=48º

Answer: ∠e=48º

8)∠f
e+f=180º
48º+f=180º
f=180º-48º
f=132º

Answer: ∠f=132º

Which term of series1 +4+7+10+...is43
Jlenok [28]

Answer:

a = 4

d = a2 - a1

d = 7 - 4

d = 3

an = 43

an = a + (n - 1)d

43 = 4 + (n - 1) 3

43 = 4 + 3n - 3

43 = 1 + 3n

43 - 1 = 3n

3n = 42

n = 42 ÷

n = 14

So, 14th term is 43

jarptica [38.1K]
Z-scores (left tail) of a given variable X are calculated by
Z(x)=(x-mean)/standard deviation.
For Mary:
Zm(124)=(124-110)/8=14/8=1.75
For Carrie:
Zc(289)=(289-250)/20=39/20=1.95
therefore

If cot 0= 4/3, find csc 0
miskamm [114]

Answer:

5/3

Step-by-step explanation:

Trigonometric ratio

Cot θ = Adjacent side/Opposite side

It is given that,

Cot θ  = 4/3

Adjacent side = 4

Opposite side = 3

Csc θ = Hypotenuse/Opposite side

To find the Hypotenuse

Hypotenuse² = Opposite side² + Adjacent side ² = 3²+ 4²

Hypotenuse = √(3²+ 4²) = 5

To find Csc θ

Csc θ = Hypotenuse/Opposite side = 5/3
