What number do u need help on?
Answer:
x = -3 and x = 1/2
Step-by-step explanation:
To find the solutions to
2x² + 5x - 3 = 0
we can use the quadratic formula, as follows:
Answer:
Option A is correct.
Step-by-step explanation:
Given an isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14. we have to find the area of isosceles trapezoid.
An isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14.
From the figure attached , we can see an isosceles trapezoid ABCD,
AB = 8cm and CD=14cm
So we have to find the value of AE which is the height of Trapezoid in order to find area.
In ΔAED
⇒
∴ AE = DE =3cm
h=3cm, a=14cm, b=8cm
hence,
Option A is correct.
The angle is the cosine inverse function because base over hypotenuse. Then the angle will be 37°.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The triangle with base of 4 units and hypotenuse of 5 units.
We know that the angle is given by the cosine inverse function because base over hypotenuse. Then we have
⇒ cos⁻¹ (4/5)
Then the angle will be
⇒ 36.869 ≈ 37°
