Answer:

assume both unknown angles as x so x+x=2x

then 180° (2x+90)=90/2

angle x =45°

another angle = 180-[90°+45°]

. 180°-135°

=45°

so angle x =45°

another angle = 45°

Image is below, please help me fast i have 2 minutes left, thank you very much
Yuki888 [10]

Answer:

45

Step-by-step explanation:

1/3 of 90

= 1/3 * 90

= 90/3

= 30

Let the missing number be x.

2/3 of x

= 2/3 * x

= 2x/3

30 = 2x/3

Cross multiply,

2x = 30 * 3

2x = 90

x = 90/2

x = 45

Hence,

the missing number is 45.
