Answer:
The value of 'x' is 17.
Step-by-step explanation:
Given:
Δ IJK ≅ ΔPQR
m∠I = 3x + 4
m∠P = 72 - x
To Find:
x = ?
Solution:
Δ IJK ≅ ΔPQR ...........Given
If two triangles are congruent then the corresponding angles of congruent triangles are congruent.
∴∠ I ≅ ∠ P ........corresponding parts of congruent triangle (CPCT)
Substituting the values we get
The value of 'x' is 17.
Answer:
B
Step-by-step explanation:
Where f(x) and g(x) intersect on the x- axis the value of y is zero
Equate either of the 2 functions to 0 and solve for x
Using f(x) = 8x² - 2, then
8x² - 2 = 0 ( add 2 to both sides )
8x² = 2 ( divide both sides by 8 )
x² = =
Take the square root of both sides
x = ± = ±
Hence k = → B
