<span>1st one: x, 2nd wud b : x+2
if its sum is 56
means:
x+ (x+2) = 56
2x = 56 -2
x= 54/2
x= 27
27 is the first odd number and the second is 27 + 2 i.e. 29
------------------------
sum of two numbers is 72
let smaller: x
larger: 4+x
its sum:
(4+x) + x = 72
4+2x=72
x= 68/2
x= 34
smaller is 34 and the larger is 34 + 4 = 38

Answer:
x=60
Step-by-step explanation:
So basically the sum of interior angle of a triangle is 180.
Add all the values and make it equal to 180.
x+3/2x+1/2x=180
Then find x
3x=180
x=180/3
x=60 degrees
Answer:
A
Step-by-step explanation:
A has 4 boxes with XS and the end result is 4 1s which add up to 4 Xs
Answer:
a= 75°
β= 30°
Step-by-step explanation:
α = 75° This is because triangle PQR isosceles. Thus two of its angles are equal and these two are angle α and the one labelled 75.
β = 30° This is because angles in a triangle sum up to 180°. We already know two of these angles. To find β you say 180 - ( 75 × 2)
The answer becomes 30°.
