4. In the following diagram, STU, RTP and RUQ are straight lines, SU is parallel to P2.
RPQ = 90°, SR = SP=9 cm, TU = 5 cm and
RU = 7 cm.
(a) Identify two triangles which are
congruent.
(b) Calculate the lengths of UQ and PQ

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
