$\boxed {\boxed {\sf 9.8}}$

Step-by-step explanation:

We are asked to find the distance between two points. We will calculate the distance using the following formula;

$d= \sqrt {(x_2-x_1)^2+(y_2-y_1)^2$

In this formula, (x₁ , y₁) and (x₂ , y₂) are the 2 points. We are given the points (4,0) and (0,9). If we match the value and the corresponding variable, we see that:

x₁= 4 y₁= 0 x₂= 0 y₂= 9

Substitute the values into the formula.

${d= \sqrt {(0-4)^2+(9-0)^2$

Solve inside the parentheses.

(0-4)= -4 (9-0)= 9

$d=\sqrt{(-4)^2+ (9)^2$

Solve the exponents. Remember that squaring a number is the same as multiplying it by itself.

(-4)²= -4*-4= 16 (9)²= 9*9= 81

$d= \sqrt{(16)+(81)$

Add.

$d= \sqrt{97$

Take the square root of the number.

d=9.848857802

Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 8 in the tenth place.

$d\approx 9.8$

The distance between the two points (4,0) and (0,9) is approximately 9.8

B has a measure of 54°.

Step-by-step explanation:

Complementary angles have a sum of 90°, so the sum of the measures of angles A and B is 90°. Subtract 36° from 90° and angle B has a measure of 54°.
