Q1
cos 59° = x/16x = 16 cos 59°x = 8.24Q2
BC is given 23 mi
Maybe AB is needed
AB = √34² + 23² = 41 (rounded)Q3
BC² = AB² - AC²BC = √(37² - 12²) = 35Q4
Let the angle is x
cos x = 19/20x = arccos (19/20)x = 18.2° (rounded)Q5
See attached
Added point D and segments AD and DC to help with calculation
BC² = BD² + DC² = (AB + AD)² + DC²Find the length of added red segments
AD = AC cos 65° = 14 cos 65° = 5.9DC = AC sin 65° = 14 sin 65° = 12.7Now we can find the value of BC
BC² = (19 + 5.9)² + 12.7²BC = √781.3BC = 28.0 ydAll calculations are rounded

Triangle 3: 9, 12, 15
Triangle 4: 12, 16, 20
Answers
Answer: Triangle 3 is not a right triangle
Step-by-step explanation:
The sides should be able to put into the Pythagorean Theorem if it is a right triangle
Triangle 1: 6, 8, 10... 36+64=100-- true statement
Triangle 2: 6, 10, 12 ... 36+100 - 144-- incorrect statement
Triangle 3: 9, 12, 15... 81+144= 225-- true Statement
Triangle 4: 12, 16, 20... 144+256=400-- true statement
Which equation has a solution of 4? Select all that apply. A 12x = 3 C10 + x = 14 B 6x = 24 DX-4 = 8
Answers
Answer:
C and B
Step-by-step explanation:
A. 12x = 3, x =1/4
C. 10 + x = 14, x = 4
B. 6x = 24, x =4
D. x -4 = 8, x =12
Only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
A
12x = 3
Simplifying the above expression,
12x = 3
x = 3 / 12
x = 1 / 4
Similarly simplifying all the expressions gives,
B. x = 4
C. x = 4
D. x = 12
Thus, only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.

257
241
227
249
Answers
Answer:
249
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
an = a1+d(n-1)
a1 is the first term so a1 = -39
d is the common difference so d = 8
n is the term number so n = 37
a37 = -39+8(37-1)
= -39+8(36)
= -39+288
=249
