Answer:

51.08 in.²

Step-by-step explanation:

S.A = (l x b) + (l × h) + (b × h)

= (8.2 in. × 3.4 in.) + (8.2 in. × 2 in.) + (3.4 in. × 2 in.)

= 27.88 in.² + 16.4 in.² + 6.8 in.²

= 51.08 in.²

Helpppp know!!!! It’s math and it is genmontry

vladimir2022 [97]

Answer:

Part 7) Adjacent angles

m<SUR and m<RUN

m<TUP and m<PUQ

Part 8) Vertical acute angles

m<SUR and m<PUQ

m<RUN and m<TUP

Part 9) Supplementary angles

m<SUT and m<TUQ

m<SUR and m<QUR

Part 10) $m$

Part 11) m<RUQ is greater than m< TUR

Part 12) $x=21\°$

Part 13) $m$

Step-by-step explanation:

Part 7) we know that

we know that

Two angles are Adjacent when they have a common side and a common vertex

In this problem

m<SUR and m<RUN ----> are adjacent angles

because have a common side UR and a common vertex U

m<TUP and m<PUQ ----> are adjacent angles

because have a common side UP and a common vertex U

Part 8) we know that

An angle is acute when is measure is less than $90$ degrees

Vertical Angles are the pair of congruent angles opposite each other when two lines cross

In this problem

$m$ ------> by vertical angles

Part 9) we know that

Two angles are supplementary if its sum is equal to $180$ degrees

In this problem

$m$ ------> by supplementary angles

Part 10) Find m<QUR

we know that

$m$ ------> by supplementary angles

we have

$m$

substitute

$41\°+m$

$m$

Part 11) which is greater m<TUR or m< RUQ

we know that

m<TUR=m<TUS+m<SUR

substitute the values

$m$

$m$ ----> see the procedure problem 10

therefore

m<RUQ is greater than m< TUR

Part 12) Find the measure angle x

$4x=84\°$ ------> by vertical angles

solve for x

$x=84\°/4=21\°$

Part 13) m<KMH

we know that

$m$ -----> by supplementary angles

$m$

NNADVOKAT [17]

Answer:

m∠LON = m∠HKJ

Step-by-step explanation:

. m∠LOM = m∠JKI; m∠MON = m∠IKH 1.

2. m∠LOM + m∠MON = m∠JKI + 2.

m∠MON

3. m∠LOM + m∠MON = m∠JKI + 3.

m∠IKH

4. m∠LOM + m∠MON = m∠LON; 4.

m∠JKI + m∠IKH = m∠HKJ

5. m∠LON = m∠HKJ 5.
