3)) which diagram shows ∠1 and ∠2 as vertical angles? A) B) C) D)
@VIJEYA
vertically opposite angles
2)
c
example |dw:1462555336749:dw| (<a ,<b) and (<c , <d) are vertically opposite angles
just go 1(a 2(c
@VIJEYA
I think that it should be 'vertically opposite angles' right? If so,then it shall be C
sum of any two angles equals to 180 are called suppllementary angles
1) how much u have to add to 20 to make 180
@dayakar which question are ya talking abt?:\
do u understand
@jirehnbush plz tell us which exactly is your question?
3) c is correct

A) 50 degrees B) 70 degrees C) 90 degrees D) 160 degrees 2)) If angle A in the diagram equals 45 degrees and angle B is 4x + 5 degrees, determine the value of x. A) 10 degrees B) 25/2degrees C) 40 degrees D) 160 degrees 3)) which diagram shows ∠1 and ∠2 as vertical angles? A) B) C) D) 44)) Angles b and c are called ____________ angles. A) complementary B) linear C) supplementary D) vertical 5)) Angle x is (2n + 12)°, and angle y is (3n + 18)° . Find the measure of angle x. Note: not drawn to scale. A) 24° B) 30° C) 72° D) 108° 66)) ∠ABC measures 124° and ∠MNO measures 56°. Therefore, the two angles are A) complementary. B) supplementary. C) congruent. D) vertical. 7)) Which statement MUST be true? A) m∠PST = m∠RPQ B) m∠TPS = m∠PQR C) m∠SPQ = m∠TPR D) m∠PQR = m∠PST 8)) If m∠A = 87° and m∠B = 32°, find m∠1. A) 29° B) 61° C) 83° D) 119° 9)) In the isosceles triangle ΔABC, AB = AC What is m∠BCD? A) 52° B) 64° C) 104° D) 116° 10)) A carpenter designs an A-frame chalkboard. Its support bars form the legs of an isosceles triangle. If the measure of base angle ABC is 75°, what is m∠BAC? A) 15° B) 30° C) 75° D) 105° 11)) If m∠A =91° and m∠B = 40°, find m∠1. A) 89° B) 122° C) 131° D) 140° 12)) Find the measure of ∠AED. A) 25° B) 65° C) 115° D) 155° 13)) 14)) What is the measurement of N? A) 138° B) 139° C) 140° D) 141° What is the measure of ∠ADC? A) 42° B) 47° C) 121° D) 131° 15)) Which set of angles are vertical angles? A) 1 and 7 B) 1 and 4 C) 2 and 4 D) 3 and 5
i mentioned question number before the solution
all of these?
1) 20 +160 = 180 160 is supplementary angle to 20
2) <A = <B 45 = 4x+5 simplify it
3) C
what are all of them
