What are the lengths of the legs of a right triangle in which one acute angle measures 19° and the hypotenuse is 15 units long?

pentagon [3]

The legs of a triangle with a hypotenuse that measures 15 units long have lengths that are equal to 15 times the sine or cosine of the given angle.
leg 1 = (15 units) x (cos 19) = 14.18 units
leg 2 = (15 units) x (sin 19) = 4.88 units
The lengths of the legs are 14.18 units and 4.88 units.

If he = 7x -27 find the value of x

Amiraneli [1.4K]

$\\ \sf\longmapsto 7x-27=1$

$\\ \sf\longmapsto 7x=1+27$

$\\ \sf\longmapsto 7x=28$

$\\ \sf\longmapsto x=\dfrac{28}{7}$

$\\ \sf\longmapsto x=4$

Answer:

Multiply each term in −1/8y≤34 by −8. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

−1/8y x −8 ≥ 34 x −8 Simplify −1/8y x −8

y ≥ 34 x −8

Multiply 34 by −8.
