Answer: f(x)=3(2)^x
Step-by-step explanation:
B. x= 50 °
C. x= 85 °
D. x= 135 °
Answer: The correct option is (A) 45.
Step-by-step explanation: We are given that triangles ABC and EFG are congruent to each other, where
We are to find the value of x.
We know that the corresponding angles of congruent triangles have equal measures.
So, m∠A = m∠E, m∠B = m∠F and m∠C = m∠G.
Also, since the sum of three angles of a triangle is 180 degrees, so from triangle ABC, we get
Thus, the required value of x is 45.
Option (A) is CORRECT.
Answer:
A. x = 45
Step-by-step explanation:
m<C = m<G = 85°
m<A + m<B + m<C = 180°
50° + x° + 85° = 180°
x = 45
B. y = 2x + 1
C. y = 5x - 1
D. y = -5x + 1
8 - 2 + 5 x ( 16 + 66 ÷ 2)
Do the ÷ in the bracket:
= 8 - 2 + 5 x ( 16 + 33)
Do the operation in the bracket:
= 8 - 2 + 5 x 49
Do multiplication:
= 8 - 2 + 245
Do subtraction:
= 6 + 245
Do addition:
= 251
