Answer:
B
Step-by-step explanation:
B: it is only a single equation
Answer:
a) angle XBC=55° because corresponding angles are congruent.
b) <BXC=70°
Step-by-step explanation:
From the diagram, XY and BD are parallel lines.
This means line AB is a transversal .
Angle XBC and angle AXY form an F-angle.
F-angles are also called corresponding angles, and are congruent.
Therefore, angle XBC=55° because corresponding angles are congruent.
b) We want to work out, angle BXC.
Since XB=XC, triangle XBC is isosceles.
The base angles of an isosceles triangles are equal.
This implies that:
<XBC=<BCX=55°.
Also, sum of angles in a triangle add up to 180°.
<XBC+<BCX+<BXC=180°
55°+55°+<BXC=180°
<BXC=180°-55°-55°
<BXC=180°-110°
<BXC=70°
Answer:
x < -39
Step-by-step explanation:
d/13 is actually just 1/13d:
1/13d > -3
Then you multiply both sides by the reciprocal of 1/13 which is 13. You do this because you normally you would divide, but since you can't divide a fraction, you multiply by the reciprocal, which is just the flipped version.
13 × 1/13 > -3 × 13
It cancels out on one side, because you are multiplying by its opposite. Then you multiply 13 × -3. This is -39. But the thing is that, when you multiply or divide by a negative, you need to flip the inequality sign around.
x < -39
5 : - 1/6 = 0.167 out of 10 = 1.67 out of 100 = 16.7
even number 0.33 out of 10:- 3.3 out of 100:- 33
a prime number 0.5 out of 10: 5 and out of 100:- 50
multipl of 3:- 0/33 out of 10:- 3.3 and out of 100: 33
Answer:
what i need to find there
Step-by-step explanation:
i only find y like an expression
Isolate the variable by dividing each side by factors that don't contain the variable.
y=sin(30t2hea+90)/2+1/16
