Answer:
D = 80 degrees or (76+4) C And F are 70 i think
Step-by-step explanation:
Answer:
∠XMZ = 74°
Step-by-step explanation:
Since the arcs XZ and BC are congruent, then
∠BNC = ∠XMZ ← substitute values
6x - 88 = 3x - 7 ( subtract 3x from both sides )
3x - 88 = - 7 ( add 88 to both sides )
3x = 81 ( divide both sides by 3 )
x = 27
Hence
∠XMZ = 3x - 7 = (3 × 27) - 7 = 81 - 7 = 74°
Answer:
x = -7 and y = 5
Step-by-step explanation:
y = 3x + 19 equation(i)
y = 5x + 33
substitute the value of y
3x + 19 = 5x + 33
3x - 5x = 33 - 19
-2x = 14
x = 14/-2
x = -7
now substitute the value of x in equation (i)
y = 3x + 19
y = 3*-7 + 19
y = -14 + 19
y = 5
Answer:
Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.
