Step-by-step explanation:

See i have answered all questions so please mark it as the brainliest please.

2. PQ=√PS²+QS²

=√(3)²+(4)²

= ✓9+16 =√25 =5cm

Therefore, tan@=perpendicular/base

=>Tan@=5/9

3.(x+5)²=2(5x-3)

=>x²+25+10x=10x-6

=>x²+0+31=0

D=(b)²-4ac

=>(0)²-4×1×31

=>-124

4. 429=3×13×11

5. 6,12,18.....

a=6 and d=6

Sⁿ=n/2{2a+(n-1)d}

S10=10/2{2×6+(10-1)6}

=5(12+54)

=5×68

=340

6.D=√(x2-x1)² + (y2-y1)²

10=√(13-5)² + (m+3)²

10=√64+m²+9+6m

(10)²=m²+73+6m

100= m² +73 +6m

m²+6m-27=0

m²+9m-6m-27=0

m(m+9)-6(m+9)=0

(m+9)(m+6)=0

Therefore, m= -9 or -6
