Answer:  32°

Explanation:

180 - 88 = 92° (Adjacent Angles on a straight line)

180 - 124 = 56° (Adjacent Angles on a straight line)

180 - 92 - 56 = 32° (Sum of angles in a triangle)

For what value of p the equation [p-3]x²+4[p-3]+4=0
Vikentia [17]

Step-by-step explanation:

(p-3)[x²+4]+4=0

(p-3)[x²+4]=-4

(p-3)=-4/x²+4

p=-4/x²+4+3

p=-4+3(x²+4)/x²+4

p= -4+3x²+12/x²+4

p=8+3x²/x²+4

Two ropes, AD and BD, are tied to a peg on the ground at point D. The other ends of the ropes are tied to points A and B on a fl
Lisa [10]

Answer: 5(√3-1) unit.

Step-by-step explanation:

Since, By the below diagram,

For triangle BDC,

We can write,

tan 30^{\circ}=\frac{BC}{DC}

⇒ \frac{1}{\sqrt{3}}=\frac{BC}{5\sqrt{3}}}

⇒  \sqrt{3}=\frac{5\sqrt{3}}{BC}

⇒ BC=\frac{5\sqrt{3} }{\sqrt{3} }

⇒ BC=5\text{ unit}

Now, In triangle ADC,

tan45^{\circ}=\frac{AC}{DC}

⇒ 1=\frac{AB+BC}{DC}

⇒ 1=\frac{DC}{AB+BC}

⇒ 1=\frac{5\sqrt{3}}{AB+5}

⇒ AB+5=5\sqrt{3}

⇒ AB=5\sqrt{3}-5=5(\sqrt{3}-1)\text{ unit}
