Answer:
the area of the problem is 20
Answer:
2√10
Step-by-step explanation:
Given the following data;
Area of square = 40
Mathematically, the area of a square is calculated by using the formula;
Area, A = s²
Where;
s is the length of sides of a square.
Substituting into the formula, we have;
40 = s²
s = √40
s = √4 * √10
s = 2 * √10
s = 2√10
The answer
the sum of the angles in a triangle is always 180°
m < B + m < A + m < C = 180°,
let's find m < B,
by applying sinus rule
14/sinB=10/sinC, so sinB= 10xsinB = 14 x sinC and therefore,
sinB=( 14/10 )sinC =7/2 sin 36° =0.82, so arcsinB=55.08°
the answer is C 55.4°
Answer:
-6
Step-by-step explanation:
1) distribute: 7x+28+6x-18=8x-24-2x+8
2)combine like-terms: 13x+10=6x-32
3)move the variable to one side: 7x+10=-32
4)subtract 10 from both sides: 7x=-42
5) divide each side by 7: x=-6
Answer:
Estimation is important because It is used to determine how reasonable a quotient is, as well as making sure its within reasonable range.
