Answer:
13°
Step-by-step explanation:
1. the two angles are equal
2. the sum of all the angles of a triangle is equal to 180°
so X+13+154=180
X+167=180
X= 180-167
X=13°
Answer:
384 .cm2
Step-by-step explanation:
Y= x+16. 16 is added to all the x numbers to come up with y.
Step-by-step explanation:
AB=BC
8x+6=6x+18
2x=12
x=6
so
AB= 48+6=54cm
BC=36+18=54cm
AD=CD
8y+20=12y-8
-4y=-28
y=7
so
AD= 84-8=76cm
CD=56+20=76cm
AE=2x+4y
AE=2×6+4×7
AE=40cm
AC=2×40=80cm
