Answer:
60°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
∠R + 88° + 32° = 180°
∠R = 60° . . . . . . subtract 120° from both sides of the equation
Answer:
55
Step-by-step explanation:
Well you just plug in 10 as n.. and you get the equation:
A(7)=1
a(20)=25
a(25)=?
a(n)=a(1)+d(n-1)
a(7)=a(1) +6d=1 -11/13+6*24/13=
a(20)=a(1)+19d=-25
a(1) +6d=1
a(1)+19d=-25 (subtract first equation from the second)
---------------------
19d-6d =-26
13d =-26
d=-2
a(1)=1-6d=1-6*(-2)=13
a(25)= a(1)+d(25-1)= 13+(-2) *24= 13-48=-35
Answer:
17.28
Step-by-step explanation:
Answer:
x = ±√10
Step-by-step explanation:
Don't you mean x^2 = 10 or x² = 10?
Taking the square root of both sides, we get:
x = ±√10 (matches first answer)
