Answer:
a = -⅓
b = 3
Step-by-step explanation:
-3a + b = 4
3a + b = 2
b = 4 + 3a = 2 - 3a
6a = -2
a = -2/6
a = - ⅓
-> b = 4 + 3(-⅓)
b = 4 - 1
b = 3
Step-by-step explanation:
In a right angle triangle one angle is 90°
w.k.t sum of angles in a triangle is 180°
thus, 2x+15+x+90°=180°
3x+105°=180°
3x=75°
x= 75/3=25°
Hope this helps you.

Step-by-step explanation:</h2>
Multiplication is when you have a number that you need to multiply by that number. Okay, let me give you an example:
2x4 means = 2+2+2+2 or 4+4
3x6 means = 3+3+3+3+3+3 or 6+6+6
the answer will always be the same.
GOOD LUCK !! :)
