Answer:
A. The value of x should be 75, because the angles shown in the diagrams are congruent.
Step-by-step explanation:
I did the test
Answer:
m=45
RPS =45
Step-by-step explanation:
the sum of angles of triangle=180 degrees
90+45+m=180
triangle PST is the image of triangle PQR
m=180-135=45 degrees
Angle RPS = 45 degrees ( two angles are adjacent when they have common side, ad do not overlap )
5. <span>15' x 15' x </span>9' = 2025 Cubic Feet<span>. so its 15
6. 1.5 * 2.5 = 3.75; 3.75 * 3 = 11.25 so it 3.75*3
7.Really the only thing that can help you is plunging in the formula
</span>
4 terms, degree of 2
The terms is the amount of “numbers” you have, which is 4
The degree is the highest power, which is x^2
Chapter : Algebra
Study : Math in Junior high school
x = 7 + √40
find √x of √x + 1
= √x + 1
= √(7+√40) + 1
in Formula is :
= √7+√40 = √x + √y
= (√7+√40)² = (√x + √y)²
= 7+√40 = x + 2√xy + y
= 7 + √40 = x + y + 2√xy
→ 7 = x + y → y = 7 - x ... Equation 1
→ √40 = 2√xy → √40 = 2.2√10 = 4√10
= xy = 10 ... Equation 2
substitution Equation 1 to 2 :
= xy = 10
= x(7-x) = 10
= 7x - x² = 10
= x² - 7x + 10 = 0
= (x - 5)(x - 2) = 0
= x = 5 or x = 2
Subsitution x = 5 and x = 2, to equation 1
#For x = 5
= y = 7 - x
= y = 7 - (5)
= y = 2
#For x = 2
= y = 7 - x
= y = 7 - (2)
= y = 5
and his x and y was find :
#Equation 1 :
= x = 5 and y = 2
#Equation 2 :
= x = 2 and y = 5
So that :
√7+√40 = √x + √y
= √7+√40 = √2 + √5
And that is answer of question :
= √2 + √5 + 1
