Answer:
To find the x-intercept, substitute in 0 for
y and solve for x. To find the y-intercept, substitute in
0
for x and solve for y.x-intercept(s): (−43,0),(52,0)y-intercept(s): (0,−20) Step-by-step explanation:
Let one leg be x. Hypotenuse = 10
x² + x² = 10²
2x² = 10²
<span>2x² = 100
</span>
<span>x² = 100/2
</span>
x² = 50
x = √50
x = √(25 *2)
x = √25 * √2 = 5√2
x = 5√2 ≈ 5*1.414 = 7.07
Length of each leg ≈ 7.07
Answer:
m∠4 = 55°
Step-by-step explanation:
From the figure attached,
m∠DBC = m∠BCA + m∠BAC [Exterior angle of a triangle equals the sum of the remote interior angles]
m∠4 = 30° + 25° = 55°
Therefore, m∠4 = 55° will be the answer.
