We are tasked to solve the three angles given that we have the measurements of the sides such as
a = Zack to Rachel distance
b = Rachel to Maddie distance
c = Maddie to Zack distance
a =3
b =2.5
c =4
Solving the angles we need to use Law of Cosines:
cos A = 2.5² + 4² -3² /2*2.5*4
A = 48.59°
cos B=3² + 4² - 2.5² / 2*3*4
B = 38.625°
C=180 - 48.59° - 38.625°
C= 92.79°
The three angles are 48.59°,38.63° and 92.79°.
Step-by-step explanation:
using SOH CAH TOA.
h=3.46 and b=4.42
Answer:
- 1364
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
4
← is an n th term
with a = 4 and r = - 2
The sum to n terms of a geometric series is
= 
, thus
= 
= 
= 
= 
= - 1364
Answer:1.) m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2.) 24° + x + m∠C = 180°
3.) x = 156° - m∠C
Step-by-step explanation:
1. m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2. 28°+x−4° + ______ = 180°
24° + x + m∠C = 180°
3) x = 180° - 24° - m∠C
x = 156° - m∠C
Answer:
2*x^3 + x^2 + x
Step-by-step explanation:
a^b = x
Then,
a^(2b) = a^b*a^b = x* x = x^2
a^(3b) = a^b*a^b*a^b = x*x*x = x^3
2*(a^3b) + (a^2b) + (a^b)
= 2*(x^3) + (x^2) + (x)
= 2*x^3 + x^2 + x
