Answer:
9°
Step-by-step explanation:
In a ∆, equal sides make equal angle to the third side. So the angle that's not mentioned is same '2'.
Sum of angles in a ∆ = 180°
80° + m/_2 + m/_2 = 180°
80° + (5x + 5) + (5x + 5) = 180°
10x + 90° = 180°
10x = 90°
x = 9°
Answer:
The solution of given equation is x = -4
Step-by-step explanation:
We are given the following in the question:
Let x be the variable such that
Relation:
The quotient of a number and 4 is negative 1
We can write the equation as:
Solution:
Thus, the solution of given equation is x = -4
Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°
Answer:
14 days
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
25n+100=450
Step 2: Subtract 100 from both sides.
25n+100−100=450−100
25n=350
Step 3: Divide both sides by 25.
25n/25 =350/25
n=14
