Answer:
y=131°
x=53°
Step-by-step explanation:
∠ ABD and ∠ BDC are supplementary.
The sum of the supplementary angles =180 °
thus y-4+x=180...........i
x and 37° are complementary, that is, they add up to 90°
Thus, x=90-37=53°
Using this value in equation 1 we obtain:
y-4°+53° =180°
y= 180°-53°+4°
y=131°
The dimensions are 6cm and 4cm

Answer:
x>-1
Step-by-step explanation:
-2x +3 < 5
Subtract 3 from each side
-2x+3-3 < 5-3
-2x < 2
Divide each side by -2
Remember that flips the inequality
-2x/-2 > 2/-2
x>-1
Answer:
A. 16
Step-by-step explanation:
The equation can be simplified to ...
2√j +14 = 3√j +10
4 = √j . . . . . add -2√j -10
16 = j . . . . . . square both sides
