Answer:
x = -200
Step-by-step explanation:
x + 75 = -125
Subtract 75 from both sides;
x = -200
Simplify:
(7/9)/(3/5)
Multiply the numerator by the reciprocal of the denominator, (7/9)/(3/5) = 7/9×5/3:
(7×5)/(9×3)
9×3 = 27:
(7×5)/27
7×5 = 35:
Answer: 35/27
Para que de 18 es la respuesta porque3×6 es 18
3. Hypotenuse 8m, the usual 45/45/90 triangle sides in ratio 1:1:√2. So we're 8/√2 = 4√2 from the wall.
Answer: 4√2 meters
4. 30/60/90 right triangle, sides in ratio 1:√3:2. Hypotenuse 50m, we're after the side opposite 60, so 50/√3 = (50/3) √3
Answer: (50/3)√3 meters
5. 45/45/90 again, ratio 1:1:√2. Leg 3 cm so hypotenuse 3√2
Answer: 3√2 cm
6. The altitude divides the triangle into two 30/60/90 triangles, ratio 1:√3:2.
The side length s of the original equilateral triangle is the hypotenuse and the altitude h is the long leg, so h= (√3/2) s.
Answer: a. 3√3 cm b. 2√3 cm c. 5√3 cm
