Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles given and equate to 180
4x - 13 + 15 + x + 18 = 180 ( simplify left side )
5x + 20 = 180 ( subtract 20 from both sides )
5x = 160 ( divide both sides by 5 )
x = 32
∠A = 4x - 13 = (4 × 32) - 13 = 128 - 13 = 115°
∠C = x + 18 = 32 + 18 = 50°
As a check : 115° + 15° + 50° = 180° ← correct
Answer:
The sides are as follows: 
Step-by-step explanation:
Starting with the side y, we can use the tan to solve for y:
The side x can be determined using sin:
So, the sides as as follows:
(you can also verify this result is correct using the Pythagorean theorem)
X^3= (125/27)
To find the answer, find the cube root of both sides
x= ∛(125/27)
∛(125/27)= (∛125)/(∛27) = 5/3
Final answer: 5/3

Minimum value of w is 20 feet.
Step-by-step explanation:
Consider the provided information.
Sharon has at most $25 to spend on her sister's birthday gift.
That means Sharon can spend not more than $25.
She already bought a knitting machine for her, which cost $14.99.
She would also like to get her sister some skeins of yarn to go with it. Each skein costs $2.75.
Let y represent the number of skeins of yarn.
Thus, the required inequality is:
Now solve the above inequality.
Skeins must be an integer.
Hence, the most number of skeins Sharon can afford to buy is 3.
ona wants to bake at most 30 loves of banana bread and nut bread for a bake sale. Each loaf of banana bread sells for $2.50 , And each loaf of nut bread sells for $2.75. Cora wants to make at least $44. Write a system of inequalities to model the situation
