Find the measure of angle A

blagie [28]

Answer:

43°

Step-by-step explanation:

(x + 53)° + (x + 74)° + 73° = 180°

(x + 53 + x + 74)° = 180° - 73°

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127

2x = - 20

x = - 20/2

x = - 10

$m\angle A = (x +53)\degree \\\\m\angle A = (-10 +53)\degree \\\\m\angle A = 43\degree \\\\$

Answer:

$4.5 \times 10^{9}$ tons.

300 times.

Step-by-step explanation:

Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.

So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e. $4.5 \times 10^{9}$ tons. (Answer)

Now, this amount is larger than $1.5 \times 10^{7}$ by $\frac{4.5 \times 10^{9} }{1.5 \times 10^{7}} = 300$ times. (Answer)
