Answer:
32/21
Step-by-step explanation:
multiply (2/3) by (7/7) and (6/7) by (3/3). (14/21) + (18/21) is (32/21)
Y=10
explanation:
-4•2= -8
2•4=8
-8+8=0
y=10
Answer:
x = 15.65 and y = 5√2
Step-by-step explanation:
To get x and y we will use the Pythagoras theorem as shown
hyp^2 = adj^2 + opp^2
x^2 = 14^2+7^2
x^2 = 196 + 49
x^2 = 245
x = √245
x = 15.65
Similarly for y;
y2 = 5^2 + 5^2
y^2 = 25 + 25
y^2 = 50
y = √2*25
y = 5√2
Hence x = 15.65 and y = 5√2
