2 answers:
Answer:
a = 65°
(what's missing for a half turn)
c = 30°
(bc same angle as upper left)
b = 85°
(bc a+b+c must be 180° in sum, as always in triangles)
please brainliest
Answer:
a = 45
b = 105
c = 30 .
Step-by-step explanation:
a + 135 = 180 {Linear pair}
a = 180 - 135
a = 45
d = 30 {Vertically opposite angles}
WA // YZ
c = d { Alternative interior anlges}
c = 30
a + b+ c = 180 {Angle sum property of triangle}
45 + b + 30 = 180
b + 75 = 180
b = 180 -75
b = 105

Given,
s=5
t=8
solution,
= 3st² - s²
= 3*5*8² - 5²
= 3*5*64 - 25
= 960 - 25
= 935
