Answer:
Measures of the two triangles DEF and PQR
are shown in the figure. Check if the
triangles are congruent. If congruent, which
of the following statements is true? Justify.
∆ DEF ≅ ∆ PQR ;
∆ DEF ≅ ∆ QPR ;
∆ DEF ≅ ∆ RPQ. First to Answer with explanation will be marked as brainliest.
Answer:
x = 9
Step-by-step explanation:
We are going to isolate x
14 - x = 5
subtract 14 from 5
-x = -9
multiply both sides by -1 to make x positive
x = 9

Answer:
S10 = 320
Step-by-step explanation:
The formula for calculating the sum of the nth term of an AP is expressed as
Sn = n/2(2a+(n-1)d))
Given
a = 4
d = 5
n = 10
S10 =10/2{2(5)+(10-1)5}
S10 =5{10+9(6)}
S10 =5{10+54}
S10 = 5(64)
S10 = 320
Hence the sum of the first ten terms of the sequence is 320
Answer:
DGF = 106
Step-by-step explanation:
Bisects means to divide in half, with two equal parts
DGF = DGE + EGF
DGE = EGF
DGF = DGE + DGE
DGF = 53+53
DGF = 106
