What Is The Length Of RT?

B

Step-by-step explanation:

AS is an angle bisector, thus the ratio of the sides of the triangle is equal to the ratio of the corresponding parts of RT, that is

= , substituting values

= ( cross- multiply )

7.5x = 31.5 ( divide both sides by 7.5 )

x = 4.2

Thus

RT = 3.5 + x = 3.5 + 4.2 = 7.7 → B

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
