If m<3 =54°. find each measure.
weqwewe [10]

Answer/Step-by-step explanation:

Given:

m<3 = 54°

m<2 = right angle

a. m<1 + m<2 + m<3 = 180° (angles in a straight line)

m<1 + 90° + 54° = 180° (substitution)

m<1 + 144° = 180°

m<1 = 180° - 144°

m<1 = 36°

b. m<2 = 90° (right angle)

c. m<4 = m<1 (vertical angles)

m<4 = 36° (substitution)

d. m<5 = m<2 (vertical angles)

m<5 = 90°

e. m<6 = m<3 (vertical angles)

m<6 = 54°

f. m<7 + m<6 = 180° (same side interior angles)

m<7 + 54° = 180° (substitution)

m<7 = 180 - 54

m<7 = 126°

g. m<8 = m<6 (alternate interior angles are congruent)

m<8 = 54°

h. m<9 = m<7 (vertical angles)

m<9 = 126°

i. m<10 = m<8 (vertical angles)

m<10 = 54°

j. m<11 = m<4 (alternate interior angles are congruent)

m<11 = 36° (substitution)

k. m<12 + m<11 = 180° (linear pair)

m<12 + 36° = 180° (substitution)

m<12 = 180° - 36°

m<12 = 144°

l. m<13 = m<11 (vertical angles)

m<13 = 36°

m. m<14 = m<12 (vertical angles)

m<14 = 144° (substitution)

Question 4
lawyer [7]

Answer:

18ft

Step-by-step explanation:

L = length

W = width

l = w + 2ft ; because the is 2 ft longer than width

The area of a rectangle is lw

You can take the first equation ( l = w + 2 ) and plug it in lw

like this: lw ---> (w+2)w = w^2+2w

then from the question you get: w^2+2w=19.25

you use the quadratic formula and get w = 3.5

then from the first equation, you get l = 3.5+ 2 so the length is 5.5

lastly, you use the perimeter formula: 2(l+w) so 2(9) = 18

so 18ft
