Question

y,z,10x,8x find the value of xyz​

Answer 1

Step-by-step explanation:

To make sure that x, y and z are more than Zero

X must be less than 10 (So X is from 1 to 9.9) so if we only accept the 0.1 differences (Becasue I am talking in business) it is only 90 chance to have value of X

X = 6.4

y = 9.6

z = 84

Answer 2

Answer:

∠PQR+ext.∠Q=180

∘

[Linear pair]

∠PQR+80

∘

=180

∘

⇒∠PQR=100

∘

x+100

∘

=180

∘

[Supplementary angles of parallelogram]

x=80

∘

In △PSR,Z=∠SRP [Alternate angles]

∴80

∘

+60

∘

+Z=180

∘

⇒Z=180
