Answer:

∠ X = 30°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinX = \frac{opposite}{hypotenuse} = \frac{YZ}{XZ} = \frac{2\sqrt{2} }{4\sqrt{2} } = \frac{2}{4} = \frac{1}{2} , then

∠ X = sin^{-1} ( \frac{1}{2} ) = 30°

Is 800 cm bigger than 8 m
Soloha48 [4]
Convert 8m to cm.

1 m = 100 cm

Multiply:

8 * 100 = 800

So 8 m is equal to 800 cm.

Both of them are equal, so 800 cm is not bigger than 8 m.

About how much difference in average leaf width would you find in two forests whose average annual rainfalls are near 1500 mm bu
goblinko [34]

Answer:

4.80 mm to 2 d.p

Step-by-step explanation:

w = f(r)

f'(r) = (dw/dr) = (0.0218 mm/mm)

So, for a small difference in rainfall of 220 mm, what is the corresponding small difference in width of leaves in the two forests given.

One definition of a derivative or a rate of change is that it is the ratio of very small differences in the dependent variable to very small differences in the independent variable.

Mathematically,

(dw/dr) = (Δw/Δr) for very small Δw and Δr.

0.0218 = (Δw/220)

Δw = 0.0218 × 220 = 4.796 mm = 4.80 mm to 2 d.p

Hope this Helps!!!
