Why you doing this ur just getting points
Answer:
Is not the answer but is how to do it. Sorry
Step-by-step explanation:
you got the value of a=2
use the formula
S=n/2 [2a+(n-1)d] then calculate d from here..
put it in t=a+(n-1)d
Answer:
b. x=sin^-1(a/c)
c. x=tan^-1(c/a)
e. y=cos^-1(c/b)
Step-by-step explanation:

Answer:
QT = 45
Step-by-step explanation:
ST = 65
SP = 26
RQ = 30
QT = 4x - 3
Given that ∆STR is similar to ∆PTQ, therefore:

Plug in the values

Solve for x


Cross multiply


Collect like terms


Divide both sides by 8


✅QT = 4x - 3
Plug in the value of x
QT = 4(12) - 3 = 48 - 3
QT = 45
