As discussed in the text, one possible performance enhancement is to do a shift and add instead of an actual multiplication. since 9 × 6, for example, can be written (2 × 2 × 2 + 1) × 6, we can calculate 9 × 6 by shifting 6 to the left three times and then adding 6 to that result. show the best way to calculate 0 × 33 × 0 × 55 using shifts and adds/subtracts. assume both inputs are 8-bit unsigned integers.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
