Answer:

50

Step-by-step explanation:

Because the first digit can only be odd, there are 5 possible numbers

(1, 3, 5, 7, and 9)

The second digit can be any number because they didn't really say anything about it, meaning there are 10 possibilities (REMEMBER! you can use 0 as the 2nd digit in a number! Just not as the first)

0 -> 9

So, 5 x 10 = 50

Hi,

From the picture you can see how 5x and 4x add up to 90°.

4x + 5x = 90°
9x = 90°
x = 10°

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.
