Answer:
a=35°
b=55°
c=110°
Step-by-step explanation:
∡a=35° because they are opposite angles by the vertex
∡a +∡b+90°=180° (by definition of internal angles of a triangle)
35°+∡b+90°=180°
∡b=180°-90°-35°
∡b=90°-35°
∡b=55°
∡c+70°=180 because they form a straight angle
∡c=110°
f(x)= 9,974.73 (1.05)x
no these are not equivalent
these aunt equivalent because 12+12 =24 and 3+3=6 not 7 or 28 so no ccx these are not equivalent
2(x+3)=18
